This is the bit accurate system C model of the FFT Variable streaming To make the executable 1. make -f Makefile.osci To run the executable ./SVSfft_model

[ ] where dw = data width tw = twiddle width nps = max FFT block size output order = 0 - bit reverse order, 1 - natural order input order = 0 - bit reverse order, 1 - natural order representation = 0 - fixed point, 1 - floating pt real input file = path to file containing the real input data, defaults to in_real imag input file = path to file containing the imag input data, defaults to in_imag blksize file = path to file containing nps for each frame, defaults to all frames of size nps inverse file = path to file containing fft(0)/ifft(1) for each frame, defaults to fft for all frames real output file = path to file where the real output data will be written, defaults to out_real imag output file = path to file where the imag output data will be written, defaults to out_imag NOTE if the input file contains real and imaginary data alternatively, then set real input file = imag input file. Similarly for the output files, i.e. if real output file = imag output file, then real and imaginary data will be written alternatively to the same file. input files are always assumed to be in natural order. (therefore if input file is in bit-reversed order, set input order to bit-reverse) eg ./SVSfftmodel 8 8 *** 1 1 0 real_input.txt imag_input.txt blksize_report.txt
