Webb6 feb. 2007 · A glance at ADI's web site shows ADSP-21367 SHARC can perform a 1024-point complex SIMD FFT in about 9200 cycles. Thus, to compute 1024 samples of outputs, one would have to do a 1024-point FFT, followed by 1024 complex multiplies, followed by a 1024-point IFFT. The complex multiplies take 2048 cycles on a SHARC processor. WebbIf that is useful I dunno. Like with the double buffers around the ffts is an extra 4k on the stack . I'm not using the TCM on the device either yes, and then the data access would be have to go through the cache. perhaps another 10%.... out of interest, my old sweetheart the ADI SHARC would do the 512 pt complex fft in perhaps 8000 cycles ?
