Re: [casper] 32 parallel inputs to fft_wideband_real

Hi Homin, For what it's worth, I can successfully run "update diagram" on a 32 input 2^10 point fft_wideband_real block (with mlib_devel b6e70b660) using all default block parameters. Xilinx 14.7, Matlab 2012b. Cheers, Jack On Mon, 11 Jan 2016 at 17:28 Homin Jiang

Re: [casper] 32 parallel inputs to fft_wideband_real

Hi Jack: I tried 128, 512, 1024, 2048 channels. When the input is 32, the fft block generates 4 stages of butterfly, it fails in generation of coeff_gen which is inside the 4th stage of butterfly. There is no line connections inside the coeff_gen blocks. regards homin On Tue, Jan 12, 2016 at

Hi Homin, What total size of FFT are you trying to do? How does the FFT fail? Cheers, Jack On Mon, 11 Jan 2016 at 00:35 Homin Jiang wrote: > Hello: > > Does anyone have the experience of the 32 simultaneous inputs to the > fft_wideband_real ? I have tried that for
