- * @defgroup BiquadCascadeDF2T Biquad Cascade IIR Filters Using a Direct Form II Transposed Structure       
- *       
- * This set of functions implements arbitrary order recursive (IIR) filters using a transposed direct form II structure.       
- * The filters are implemented as a cascade of second order Biquad sections.       
- * These functions provide a slight memory savings as compared to the direct form I Biquad filter functions.      
- * Only floating-point data is supported.       
- *       
- * This function operate on blocks of input and output data and each call to the function       
- * processes blockSize samples through the filter.       
- * pSrc points to the array of input data and       
- * pDst points to the array of output data.       
- * Both arrays contain blockSize values.       
- *       
- * \par Algorithm       
- * Each Biquad stage implements a second order filter using the difference equation:       
- * 
       
- *    y[n] = b0 * x[n] + d1       
- *    d1 = b1 * x[n] + a1 * y[n] + d2       
- *    d2 = b2 * x[n] + a2 * y[n]       
- * 
       
- * where d1 and d2 represent the two state values.       
- *       
- * \par       
- * A Biquad filter using a transposed Direct Form II structure is shown below.       
- * \image html BiquadDF2Transposed.gif "Single transposed Direct Form II Biquad"       
- * Coefficients b0, b1, and b2  multiply the input signal x[n] and are referred to as the feedforward coefficients.       
- * Coefficients a1 and a2 multiply the output signal y[n] and are referred to as the feedback coefficients.       
- * Pay careful attention to the sign of the feedback coefficients.       
- * Some design tools flip the sign of the feedback coefficients:       
- * 
       
- *    y[n] = b0 * x[n] + d1;       
- *    d1 = b1 * x[n] - a1 * y[n] + d2;       
- *    d2 = b2 * x[n] - a2 * y[n];       
- * 
       
- * In this case the feedback coefficients a1 and a2 must be negated when used with the CMSIS DSP Library.       
- *       
- * \par       
- * Higher order filters are realized as a cascade of second order sections.       
- * numStages refers to the number of second order stages used.       
- * For example, an 8th order filter would be realized with numStages=4 second order stages.       
- * A 9th order filter would be realized with numStages=5 second order stages with the       
- * coefficients for one of the stages configured as a first order filter (b2=0 and a2=0).       
- *       
- * \par       
- * pState points to the state variable array.       
- * Each Biquad stage has 2 state variables d1 and d2.       
- * The state variables are arranged in the pState array as:       
- * 
       
- *     {d11, d12, d21, d22, ...}       
- * 
       
- * where d1x refers to the state variables for the first Biquad and       
- * d2x refers to the state variables for the second Biquad.       
- * The state array has a total length of 2*numStages values.       
- * The state variables are updated after each block of data is processed; the coefficients are untouched.       
- *       
- * \par       
- * The CMSIS library contains Biquad filters in both Direct Form I and transposed Direct Form II.    
- * The advantage of the Direct Form I structure is that it is numerically more robust for fixed-point data types.    
- * That is why the Direct Form I structure supports Q15 and Q31 data types.    
- * The transposed Direct Form II structure, on the other hand, requires a wide dynamic range for the state variables d1 and d2.    
- * Because of this, the CMSIS library only has a floating-point version of the Direct Form II Biquad.    
- * The advantage of the Direct Form II Biquad is that it requires half the number of state variables, 2 rather than 4, per Biquad stage.    
- *       
- * \par Instance Structure       
- * The coefficients and state variables for a filter are stored together in an instance data structure.       
- * A separate instance structure must be defined for each filter.       
- * Coefficient arrays may be shared among several instances while state variable arrays cannot be shared.       
- *       
- * \par Init Functions       
- * There is also an associated initialization function.      
- * The initialization function performs following operations:       
- * - Sets the values of the internal structure fields.       
- * - Zeros out the values in the state buffer.       
- *       
- * \par       
- * Use of the initialization function is optional.       
- * However, if the initialization function is used, then the instance structure cannot be placed into a const data section.       
- * To place an instance structure into a const data section, the instance structure must be manually initialized.       
- * Set the values in the state buffer to zeros before static initialization.       
- * For example, to statically initialize the instance structure use       
- * 
       
- *     arm_biquad_cascade_df2T_instance_f32 S1 = {numStages, pState, pCoeffs};       
- * 
       
- * where numStages is the number of Biquad stages in the filter; pState is the address of the state buffer.       
- * pCoeffs is the address of the coefficient buffer;

- *  
- * This set of functions implements Finite Impulse Response (FIR) filters

- * The functions operate on blocks of input and output data and each call to the function processes  
- * blockSize samples through the filter.  pSrc and  
- * pDst points to input and output arrays containing blockSize values.  
- *  
- * \par Algorithm:  
- * The FIR filter algorithm is based upon a sequence of multiply-accumulate (MAC) operations.  
- * Each filter coefficient b[n] is multiplied by a state variable which equals a previous input sample x[n].  
- * 
  
- *    y[n] = b[0] * x[n] + b[1] * x[n-1] + b[2] * x[n-2] + ...+ b[numTaps-1] * x[n-numTaps+1]

- * pCoeffs points to a coefficient array of size numTaps.  
- * Coefficients are stored in time reversed order.

- * \par  
- * Note that the length of the state buffer exceeds the length of the coefficient array by blockSize-1.  
- * The increased state buffer length allows circular addressing, which is traditionally used in the FIR filters,  
- * to be avoided and yields a significant speed improvement.  
- * The state variables are updated after each block of data is processed; the coefficients are untouched.  
- * \par Instance Structure  
- * The coefficients and state variables for a filter are stored together in an instance data structure.  
- * A separate instance structure must be defined for each filter.  
- * Coefficient arrays may be shared among several instances while state variable arrays cannot be shared.  
- * There are separate instance structure declarations for each of the 4 supported data types.  
- *  
- * \par Initialization Functions  
- * There is also an associated initialization function for each data type.  
- * The initialization function performs the following operations:  
- * - Sets the values of the internal structure fields.  
- * - Zeros out the values in the state buffer.  
- *  
- * \par  
- * Use of the initialization function is optional.  
- * However, if the initialization function is used, then the instance structure cannot be placed into a const data section.  
- * To place an instance structure into a const data section, the instance structure must be manually initialized.

+*   
+* \par
+* The Fast Fourier Transform (FFT) is an efficient algorithm for computing the
+* Discrete Fourier Transform (DFT).  The FFT can be orders of magnitude faster
+* than the DFT, especially for long lengths.
+* The algorithms described in this section
+* operate on complex data.  A separate set of functions is devoted to handling
+* of real sequences.
+* \par
+* There are separate algorithms for handling floating-point, Q15, and Q31 data
+* types.  The algorithms available for each data type are described next.
+* \par
+* The FFT functions operate in-place.  That is, the array holding the input data
+* will also be used to hold the corresponding result.  The input data is complex
+* and contains 2*fftLen interleaved values as shown below.
+* 
 {real[0], imag[0], real[1], imag[1],..} 

+* The FFT result will be contained in the same array and the frequency domain
+* values will have the same interleaving.
+*
+* \par Floating-point
+* The floating-point complex FFT uses a mixed-radix algorithm.  Multiple radix-8
+* stages are performed along with a single radix-2 or radix-4 stage, as needed.
+* The algorithm supports lengths of [16, 32, 64, ..., 4096] and each length uses
+* a different twiddle factor table.  
+* \par
+* The function uses the standard FFT definition and output values may grow by a
+* factor of fftLen when computing the forward transform.  The
+* inverse transform includes a scale of 1/fftLen as part of the
+* calculation and this matches the textbook definition of the inverse FFT.
+* \par
+* Preinitialized data structures containing twiddle factors and bit reversal
+* tables are provided and defined in arm_const_structs.h.  Include 
+* this header in your function and then pass one of the constant structures as 
+* an argument to arm_cfft_f32.  For example:
+* \par
+* arm_cfft_f32(arm_cfft_sR_f32_len64, pSrc, 1, 1)
+* \par
+* computes a 64-point inverse complex FFT including bit reversal.
+* The data structures are treated as constant data and not modified during the
+* calculation.  The same data structure can be reused for multiple transforms
+* including mixing forward and inverse transforms.
+* \par
+* Earlier releases of the library provided separate radix-2 and radix-4
+* algorithms that operated on floating-point data.  These functions are still
+* provided but are deprecated.  The older functions are slower and less general
+* than the new functions.
+* \par
+* An example of initialization of the constants for the arm_cfft_f32 function follows:
+* \par
+* const static arm_cfft_instance_f32 *S;
+* ...
+*		switch (length) {
+*    		case 16:
+*    			S = & arm_cfft_sR_f32_len16;
+*    		break;
+*    		case 32:
+*    			S = & arm_cfft_sR_f32_len32;
+*    		break;
+*			case 64:
+*    			S = & arm_cfft_sR_f32_len64;
+*    		break;
+*    		case 128:
+*    			S = & arm_cfft_sR_f32_len128;
+*    		break;
+*    		case 256:
+*    			S = & arm_cfft_sR_f32_len256;
+*    		break;
+*    		case 512:
+*    			S = & arm_cfft_sR_f32_len512;
+*    		break;
+*    		case 1024:
+*    			S = & arm_cfft_sR_f32_len1024;
+*    		break;
+*    		case 2048:
+*    			S = & arm_cfft_sR_f32_len2048;
+*    		break;
+*    		case 4096:
+*    			S = & arm_cfft_sR_f32_len4096;
+*    		break;
+*			}
+* \par Q15 and Q31
+* The library provides radix-2 and radix-4 FFT algorithms for fixed-point data.  The
+* radix-2 algorithm supports lengths of [16, 32, 64, ..., 4096].  The radix-4
+* algorithm supports lengths of [16, 64, 256, ..., 4096].  When possible, you
+* should use the radix-4 algorithm since it is faster than the radix-2 of the
+* same length.
+* \par
+* The forward FFTs include scaling in order to prevent results from overflowing.
+* Intermediate results are scaled down during each butterfly stage.  In the
+* radix-2 algorithm, a scale of 0.5 is applied during each butterfly.  In the
+* radix-4 algorithm, a scale of 0.25 is applied.  The scaling applies to both
+* the forward and the inverse FFTs.  Thus the forward FFT contains an additional
+* scale factor of 1/fftLen as compared to the standard textbook
+* definition of the FFT.  The inverse FFT also scales down during each butterfly
+* stage and this corresponds to the standard textbook definition.
+* \par
+* A separate instance structure must be defined for each transform used but
+* twiddle factor and bit reversal tables can be reused.
+* \par 
+* There is also an associated initialization function for each data type.   
+* The initialization function performs the following operations:   
+* - Sets the values of the internal structure fields.   
+* - Initializes twiddle factor table and bit reversal table pointers.
+* \par   
+* Use of the initialization function is optional.   
+* However, if the initialization function is used, then the instance structure 
+* cannot be placed into a const data section. To place an instance structure 
+* into a const data section, the instance structure should be manually 
+* initialized as follows:
+* 
   
+*arm_cfft_radix2_instance_q31 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};   
+*arm_cfft_radix2_instance_q15 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};   
+*arm_cfft_radix4_instance_q31 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};    
+*arm_cfft_radix4_instance_q15 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};    
+*arm_cfft_instance_f32 S = {fftLen, pTwiddle, pBitRevTable, bitRevLength};
+* 
   
+* \par   
+* where fftLen length of CFFT/CIFFT; ifftFlag Flag for
+* selection of forward or inverse transform.  When ifftFlag is set the inverse
+* transform is calculated.
+* bitReverseFlag Flag for selection of output order (Set bitReverseFlag to output in normal order otherwise output in bit reversed order);    
+* pTwiddlepoints to array of twiddle coefficients; pBitRevTable points to the bit reversal table.   
+* twidCoefModifier modifier for twiddle factor table which supports all FFT lengths with same table;    
+* pBitRevTable modifier for bit reversal table which supports all FFT lengths with same table.   
+* onebyfftLen value of 1/fftLen to calculate CIFFT;
+* \par
+* The Q15 and Q31 FFT functions use a large bit reversal and twiddle factor
+* table.  The tables are defined for the maximum length transform and a subset
+* of the coefficients are used in shorter transforms.

- * 
 {real[0], imag[0], real[1], imag[1],..} 
   
- *   
- * \par Lengths supported by the transform:  
- * \par   
- * Internally, the function utilize a radix-2 decimation in frequency(DIF) algorithm   
- * and the size of the FFT supported are of the lengths [16, 32, 64, 128, 256, 512, 1024, 2048, 4096].  
- *    
- *   
- * \par Algorithm:   
- *   
- * Complex Fast Fourier Transform:   
- * \par    
- * Input real and imaginary data:   
- * 
   
- * x(n) = xa + j * ya   
- * x(n+N/2 ) = xb + j * yb   
- * 
   
- * where N is length of FFT   
- * \par   
- * Output real and imaginary data:   
- * 
   
- * X(2r) = xa'+ j * ya'   
- * X(2r+1) = xb'+ j * yb'   
- * 
   
- * \par   
- * Twiddle factors for radix-2 FFT:   
- * 
   
- * Wn = cosVal + j * (- sinVal)   
- * 
   
- *   
- * \par   
- * \image html CFFT_Radix2.gif "Radix-2 Decimation-in Frequency Complex Fast Fourier Transform"   
- *   
- * \par   
- * Output from Radix-2 CFFT Results in Digit reversal order. Interchange middle two branches of every butterfly results in Bit reversed output.   
- * \par   
- *  Butterfly CFFT equations:   
- * 
   
- * xa' = xa + xb  
- * ya' = ya + yb  
- * xb' = (xa-xb)* cosVal + (ya-yb) * sinVal

- * Complex Inverse Fast Fourier Transform:   
- * \par   
- * CIFFT uses same twiddle factor table as CFFT with modifications in the design equation as shown below.   
- *   
- * \par   
- *  Modified Butterfly CIFFT equations:   
- * 
   
- * xa' = xa + xb  
- * ya' = ya + yb  
- * xb' = (xa-xb)* cosVal - (ya-yb) * sinVal   
- * yb' = (ya-yb)* cosVal + (xa-xb) * sinVal   
- * 
   
- *   
- * \par Instance Structure   
- * A separate instance structure must be defined for each Instance but the twiddle factors and bit reversal tables can be reused.   
- * There are separate instance structure declarations for each of the 3 supported data types.   
- *   
- * \par Initialization Functions   
- * There is also an associated initialization function for each data type.   
- * The initialization function performs the following operations:   
- * - Sets the values of the internal structure fields.   
- * - Initializes twiddle factor table and bit reversal table pointers   
- * \par   
- * Use of the initialization function is optional.   
- * However, if the initialization function is used, then the instance structure cannot be placed into a const data section.   
- * To place an instance structure into a const data section, the instance structure must be manually initialized.   
- * Manually initialize the instance structure as follows:   
- * 
   
- *arm_cfft_radix2_instance_f32 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor, onebyfftLen};   
- *arm_cfft_radix2_instance_q31 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};   
- *arm_cfft_radix2_instance_q15 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};   
- * 
   
- * \par   
- * where fftLen length of CFFT/CIFFT; ifftFlag Flag for selection of CFFT or CIFFT(Set ifftFlag to calculate CIFFT otherwise calculates CFFT);   
- * bitReverseFlag Flag for selection of output order(Set bitReverseFlag to output in normal order otherwise output in bit reversed order);    
- * pTwiddlepoints to array of twiddle coefficients; pBitRevTable points to the array of bit reversal table.   
- * twidCoefModifier modifier for twiddle factor table which supports all FFT lengths with same table;    
- * pBitRevTable modifier for bit reversal table which supports all FFT lengths with same table.   
- * onebyfftLen value of 1/fftLen to calculate CIFFT;   
- *  
- * \par Fixed-Point Behavior   
- * Care must be taken when using the fixed-point versions of the CFFT/CIFFT function.   
- * Refer to the function specific documentation below for usage guidelines.

- *    
- * \par    
- * Complex Fast Fourier Transform(CFFT) and Complex Inverse Fast Fourier Transform(CIFFT) is an efficient algorithm to compute Discrete Fourier Transform(DFT) and Inverse Discrete Fourier Transform(IDFT).    
- * Computational complexity of CFFT reduces drastically when compared to DFT.    
- * \par    
- * This set of functions implements CFFT/CIFFT    
- * for Q15, Q31, and floating-point data types.  The functions operates on in-place buffer which uses same buffer for input and output.    
- * Complex input is stored in input buffer in an interleaved fashion.    
- *    
- * \par    
- * The functions operate on blocks of input and output data and each call to the function processes    
- * 2*fftLen samples through the transform.  pSrc  points to In-place arrays containing 2*fftLen values.    
- * \par   
- * The pSrc points to the array of in-place buffer of size 2*fftLen and inputs and outputs are stored in an interleaved fashion as shown below.    
- * 
 {real[0], imag[0], real[1], imag[1],..} 
    
- *    
- * \par Lengths supported by the transform:   
- * \par    
- * Internally, the function utilize a radix-4 decimation in frequency(DIF) algorithm    
- * and the size of the FFT supported are of the lengths [16, 64, 256, 1024].   
- *     
- *    
- * \par Algorithm:    
- *    
- * Complex Fast Fourier Transform:    
- * \par     
- * Input real and imaginary data:    
- * 
    
- * x(n) = xa + j * ya    
- * x(n+N/4 ) = xb + j * yb    
- * x(n+N/2 ) = xc + j * yc    
- * x(n+3N 4) = xd + j * yd    
- * 
    
- * where N is length of FFT    
- * \par    
- * Output real and imaginary data:    
- * 
    
- * X(4r) = xa'+ j * ya'    
- * X(4r+1) = xb'+ j * yb'    
- * X(4r+2) = xc'+ j * yc'    
- * X(4r+3) = xd'+ j * yd'    
- * 
    
- * \par    
- * Twiddle factors for radix-4 FFT:    
- * 
    
- * Wn = co1 + j * (- si1)    
- * W2n = co2 + j * (- si2)    
- * W3n = co3 + j * (- si3)    
- *

- * \image html CFFT.gif "Radix-4 Decimation-in Frequency Complex Fast Fourier Transform"    
- *    
- * \par    
- * Output from Radix-4 CFFT Results in Digit reversal order. Interchange middle two branches of every butterfly results in Bit reversed output.    
- * \par    
- *  Butterfly CFFT equations:    
- * 
    
- * xa' = xa + xb + xc + xd    
- * ya' = ya + yb + yc + yd    
- * xc' = (xa+yb-xc-yd)* co1 + (ya-xb-yc+xd)* (si1)    
- * yc' = (ya-xb-yc+xd)* co1 - (xa+yb-xc-yd)* (si1)    
- * xb' = (xa-xb+xc-xd)* co2 + (ya-yb+yc-yd)* (si2)    
- * yb' = (ya-yb+yc-yd)* co2 - (xa-xb+xc-xd)* (si2)    
- * xd' = (xa-yb-xc+yd)* co3 + (ya+xb-yc-xd)* (si3)    
- * yd' = (ya+xb-yc-xd)* co3 - (xa-yb-xc+yd)* (si3)    
- * 
    
- *    
- *    
- * Complex Inverse Fast Fourier Transform:    
- * \par    
- * CIFFT uses same twiddle factor table as CFFT with modifications in the design equation as shown below.    
- *    
- * \par    
- *  Modified Butterfly CIFFT equations:    
- * 
    
- * xa' = xa + xb + xc + xd    
- * ya' = ya + yb + yc + yd    
- * xc' = (xa-yb-xc+yd)* co1 - (ya+xb-yc-xd)* (si1)    
- * yc' = (ya+xb-yc-xd)* co1 + (xa-yb-xc+yd)* (si1)    
- * xb' = (xa-xb+xc-xd)* co2 - (ya-yb+yc-yd)* (si2)    
- * yb' = (ya-yb+yc-yd)* co2 + (xa-xb+xc-xd)* (si2)    
- * xd' = (xa+yb-xc-yd)* co3 - (ya-xb-yc+xd)* (si3)    
- * yd' = (ya-xb-yc+xd)* co3 + (xa+yb-xc-yd)* (si3)    
- * 
    
- *    
- * \par Instance Structure    
- * A separate instance structure must be defined for each Instance but the twiddle factors and bit reversal tables can be reused.    
- * There are separate instance structure declarations for each of the 3 supported data types.    
- *    
- * \par Initialization Functions    
- * There is also an associated initialization function for each data type.    
- * The initialization function performs the following operations:    
- * - Sets the values of the internal structure fields.    
- * - Initializes twiddle factor table and bit reversal table pointers    
- * \par    
- * Use of the initialization function is optional.    
- * However, if the initialization function is used, then the instance structure cannot be placed into a const data section.    
- * To place an instance structure into a const data section, the instance structure must be manually initialized.    
- * Manually initialize the instance structure as follows:    
- * 
    
- *arm_cfft_radix4_instance_f32 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor, onebyfftLen};    
- *arm_cfft_radix4_instance_q31 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};    
- *arm_cfft_radix4_instance_q15 S = {fftLen, ifftFlag, bitReverseFlag, pTwiddle, pBitRevTable, twidCoefModifier, bitRevFactor};    
- * 
    
- * \par    
- * where fftLen length of CFFT/CIFFT; ifftFlag Flag for selection of CFFT or CIFFT(Set ifftFlag to calculate CIFFT otherwise calculates CFFT);    
- * bitReverseFlag Flag for selection of output order(Set bitReverseFlag to output in normal order otherwise output in bit reversed order);     
- * pTwiddlepoints to array of twiddle coefficients; pBitRevTable points to the array of bit reversal table.    
- * twidCoefModifier modifier for twiddle factor table which supports all FFT lengths with same table;     
- * pBitRevTable modifier for bit reversal table which supports all FFT lengths with same table.    
- * onebyfftLen value of 1/fftLen to calculate CIFFT;    
- *   
- * \par Fixed-Point Behavior    
- * Care must be taken when using the fixed-point versions of the CFFT/CIFFT function.    
- * Refer to the function specific documentation below for usage guidelines.

+* Complex Fast Fourier Transform(CFFT) and Complex Inverse Fast Fourier Transform(CIFFT) is an efficient algorithm to compute Discrete Fourier Transform(DFT) and Inverse Discrete Fourier Transform(IDFT).    
+* Computational complexity of CFFT reduces drastically when compared to DFT.    
+* \par    
+* This set of functions implements CFFT/CIFFT    
+* for floating-point data types.  The functions operates on in-place buffer which uses same buffer for input and output.    
+* Complex input is stored in input buffer in an interleaved fashion.    
+*    
+* \par    
+* The functions operate on blocks of input and output data and each call to the function processes    
+* 2*fftLen samples through the transform.  pSrc  points to In-place arrays containing 2*fftLen values.    
+* \par   
+* The pSrc points to the array of in-place buffer of size 2*fftLen and inputs and outputs are stored in an interleaved fashion as shown below.    
+* 
 {real[0], imag[0], real[1], imag[1],..} 
    
+*    
+* \par Lengths supported by the transform:   
+* \par    
+* Internally, the function utilize a Radix-8 decimation in frequency(DIF) algorithm    
+* and the size of the FFT supported are of the lengths [ 64, 512, 4096].

- * @defgroup RFFT_RIFFT Real FFT Functions    
- *    
- * \par    
- * Complex FFT/IFFT typically assumes complex input and output. However many applications use real valued data in time domain.     
- * Real FFT/IFFT efficiently process real valued sequences with the advantage of requirement of low memory and with less complexity.    
- *    
- * \par    
- * This set of functions implements Real Fast Fourier Transforms(RFFT) and Real Inverse Fast Fourier Transform(RIFFT)    
- * for Q15, Q31, and floating-point data types.      
- *    
- *    
- * \par Algorithm:    
- *    
- * Real Fast Fourier Transform:    
- * \par    
- * Real FFT of N-point is calculated using CFFT of N/2-point and Split RFFT process as shown below figure.    
- * \par    
- * \image html RFFT.gif "Real Fast Fourier Transform"    
- * \par    
- * The RFFT functions operate on blocks of input and output data and each call to the function processes    
- * fftLenR samples through the transform.  pSrc  points to input array containing fftLenR values.    
- * pDst  points to output array containing 2*fftLenR values. \n   
- * Input for real FFT is in the order of     
- * 
{real[0], real[1], real[2], real[3], ..}
    
- * Output for real FFT is complex and are in the order of    
- * 
{real(0), imag(0), real(1), imag(1), ...}
     
- *    
- * Real Inverse Fast Fourier Transform:    
- * \par    
- * Real IFFT of N-point is calculated using Split RIFFT process and CFFT of N/2-point as shown below figure.    
- * \par    
- * \image html RIFFT.gif "Real Inverse Fast Fourier Transform"    
- * \par    
- * The RIFFT functions operate on blocks of input and output data and each call to the function processes    
- * 2*fftLenR samples through the transform.  pSrc  points to input array containing 2*fftLenR values.    
- * pDst  points to output array containing fftLenR values. \n    
- * Input for real IFFT is complex and are in the order of   
- * 
{real(0), imag(0), real(1), imag(1), ...}
   
- *  Output for real IFFT is real and in the order of     
- * 
{real[0], real[1], real[2], real[3], ..}
   
- *    
- * \par Lengths supported by the transform:   
- * \par    
- * Real FFT/IFFT supports the lengths [128, 512, 2048], as it internally uses CFFT/CIFFT.    
- *    
- * \par Instance Structure    
- * A separate instance structure must be defined for each Instance but the twiddle factors can be reused.    
- * There are separate instance structure declarations for each of the 3 supported data types.    
- *    
- * \par Initialization Functions    
- * There is also an associated initialization function for each data type.    
- * The initialization function performs the following operations:    
- * - Sets the values of the internal structure fields.    
- * - Initializes twiddle factor tables.   
- * - Initializes CFFT data structure fields.     
- * \par    
- * Use of the initialization function is optional.    
- * However, if the initialization function is used, then the instance structure cannot be placed into a const data section.    
- * To place an instance structure into a const data section, the instance structure must be manually initialized.    
- * Manually initialize the instance structure as follows:    
- * 
    
- *arm_rfft_instance_f32 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
- *arm_rfft_instance_q31 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
- *arm_rfft_instance_q15 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
- * 
    
- * where fftLenReal length of RFFT/RIFFT; fftLenBy2 length of CFFT/CIFFT.     
- * ifftFlagR Flag for selection of RFFT or RIFFT(Set ifftFlagR to calculate RIFFT otherwise calculates RFFT);    
- * bitReverseFlagR Flag for selection of output order(Set bitReverseFlagR to output in normal order otherwise output in bit reversed order);     
- * twidCoefRModifier modifier for twiddle factor table which supports 128, 512, 2048 RFFT lengths with same table;    
- * pTwiddleARealpoints to A array of twiddle coefficients; pTwiddleBRealpoints to B array of twiddle coefficients;    
- * pCfft points to the CFFT Instance structure. The CFFT structure also needs to be initialized, refer to arm_cfft_radix4_f32() for details regarding    
- * static initialization of cfft structure.    
- *    
- * \par Fixed-Point Behavior    
- * Care must be taken when using the fixed-point versions of the RFFT/RIFFT function.    
- * Refer to the function specific documentation below for usage guidelines.

+ * @defgroup Fast Real FFT Functions
+ *
+ * \par
+ * The CMSIS DSP library includes specialized algorithms for computing the
+ * FFT of real data sequences.  The FFT is defined over complex data but
+ * in many applications the input is real.  Real FFT algorithms take advantage
+ * of the symmetry properties of the FFT and have a speed advantage over complex
+ * algorithms of the same length.
+ * \par
+ * The Fast RFFT algorith relays on the mixed radix CFFT that save processor usage.
+ * \par
+ * The real length N forward FFT of a sequence is computed using the steps shown below.
+ * \par
+ * \image html RFFT.gif "Real Fast Fourier Transform"
+ * \par
+ * The real sequence is initially treated as if it were complex to perform a CFFT.
+ * Later, a processing stage reshapes the data to obtain half of the frequency spectrum
+ * in complex format. Except the first complex number that contains the two real numbers
+ * X[0] and X[N/2] all the data is complex. In other words, the first complex sample
+ * contains two real values packed.
+ * \par
+ * The input for the inverse RFFT should keep the same format as the output of the 
+ * forward RFFT. A first processing stage pre-process the data to later perform an
+ * inverse CFFT.
+ * \par    
+ * \image html RIFFT.gif "Real Inverse Fast Fourier Transform"    
+ * \par    
+ * The algorithms for floating-point, Q15, and Q31 data are slightly different
+ * and we describe each algorithm in turn.
+ * \par Floating-point
+ * The main functions are arm_rfft_fast_f32()
+ * and arm_rfft_fast_init_f32().  The older functions
+ * arm_rfft_f32() and arm_rfft_init_f32() have been
+ * deprecated but are still documented.
+ * \par
+ * The FFT of a real N-point sequence has even symmetry in the frequency
+ * domain.  The second half of the data equals the conjugate of the first half
+ * flipped in frequency:
+ * 
+ *X[0] - real data
+ *X[1] - complex data
+ *X[2] - complex data
+ *... 
+ *X[fftLen/2-1] - complex data
+ *X[fftLen/2] - real data
+ *X[fftLen/2+1] - conjugate of X[fftLen/2-1]
+ *X[fftLen/2+2] - conjugate of X[fftLen/2-2]
+ *... 
+ *X[fftLen-1] - conjugate of X[1]
+ * 

+ * Looking at the data, we see that we can uniquely represent the FFT using only
+ * 
+ *N/2+1 samples:
+ *X[0] - real data
+ *X[1] - complex data
+ *X[2] - complex data
+ *... 
+ *X[fftLen/2-1] - complex data
+ *X[fftLen/2] - real data
+ * 

+ * Looking more closely we see that the first and last samples are real valued.
+ * They can be packed together and we can thus represent the FFT of an N-point
+ * real sequence by N/2 complex values:
+ * 
+ *X[0],X[N/2] - packed real data: X[0] + jX[N/2]
+ *X[1] - complex data
+ *X[2] - complex data
+ *... 
+ *X[fftLen/2-1] - complex data
+ * 

+ * The real FFT functions pack the frequency domain data in this fashion.  The
+ * forward transform outputs the data in this form and the inverse transform
+ * expects input data in this form.  The function always performs the needed
+ * bitreversal so that the input and output data is always in normal order.  The 
+ * functions support lengths of [32, 64, 128, ..., 4096] samples.
+ * \par
+ * The forward and inverse real FFT functions apply the standard FFT scaling; no
+ * scaling on the forward transform and 1/fftLen scaling on the inverse
+ * transform.
+ * \par Q15 and Q31
+ * The real algorithms are defined in a similar manner and utilize N/2 complex
+ * transforms behind the scenes.  In the case of fixed-point data, a radix-4
+ * complex transform is performed and this limits the allows sequence lengths to
+ * 128, 512, and 2048 samples.
+ * \par
+ * TBD.  We need to document input and output order of data.
+ * \par
+ * The complex transforms used internally include scaling to prevent fixed-point
+ * overflows.  The overall scaling equals 1/(fftLen/2).
+ * \par
+ * A separate instance structure must be defined for each transform used but 
+ * twiddle factor and bit reversal tables can be reused.
+ * \par
+ * There is also an associated initialization function for each data type. 
+ * The initialization function performs the following operations:
+ * - Sets the values of the internal structure fields.   
+ * - Initializes twiddle factor table and bit reversal table pointers.
+ * - Initializes the internal complex FFT data structure.
+ * \par   
+ * Use of the initialization function is optional.   
+ * However, if the initialization function is used, then the instance structure 
+ * cannot be placed into a const data section. To place an instance structure 
+ * into a const data section, the instance structure should be manually 
+ * initialized as follows:
+ * 
+ *arm_rfft_instance_q31 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
+ *arm_rfft_instance_q15 S = {fftLenReal, fftLenBy2, ifftFlagR, bitReverseFlagR, twidCoefRModifier, pTwiddleAReal, pTwiddleBReal, pCfft};    
+ * 

+ * where fftLenReal is the length of the real transform;
+ * fftLenBy2 length of  the internal complex transform.
+ * ifftFlagR Selects forward (=0) or inverse (=1) transform.
+ * bitReverseFlagR Selects bit reversed output (=0) or normal order
+ * output (=1).
+ * twidCoefRModifier stride modifier for the twiddle factor table.
+ * The value is based on the FFT length;
+ * pTwiddleARealpoints to the A array of twiddle coefficients; 
+ * pTwiddleBRealpoints to the B array of twiddle coefficients;    
+ * pCfft points to the CFFT Instance structure. The CFFT structure
+ * must also be initialized.  Refer to arm_cfft_radix4_f32() for details regarding    
+ * static initialization of the complex FFT instance structure.

Subject: [PATCH 45/72] Increase available RAM for RTX on LPC11U24

The INITIAL_SP value used by RTX was originally at the 4k limit instead
of at the 8k limit.  The HEAP_START macro was defined to __HeapLimit
but the heap really starts at __end__.  __HeapLimit is just used for
some link time sanity checks to verify that the heap and stack can
grow a bit without colliding.

Subject: [PATCH 46/72] support GCC_ARM for LPC4330_M4

 - Linker script is based on LPC1768
     number of NVIC is 16 (CORE) + 53 (M4 in LPC43xx) = 69,
    therefor, reserve at the top of RAM0 (address:0x10000000)
    to relocate NVIC vector table
 - startup file is based on startup_ARMCM4.S in CMSIS V3.20
     change NVIC name for cortex-M4 of LPC43xx
 - add GCC_ARM for LPC4330_M4 in python scripts
 - add some descriptions for GCC_ARM
