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. incognito mode for flights https://fourde-mattress.com

Since the real FFT requires about 12 clock cycles per sample, FFT convolution can be carried out in about 60 clock cycles per sample. For a 2106x SHARC DSP at 40 MHz, this corresponds to a data throughput of approximately 660k samples/second.
