I think the answer is no -- but I thought I'd ask anyway
I presume the FFT acclerator on the SHARC works with signals of length that are 'precisely' powers of 2 (e.g. 512, 1024)
I have a need to do more custom FFT length -- say 980 -- and no, I don't want to pad with zeros to 1024 as that distorts everything.
Is there anything I can do -- 980 is 2 * 2 * 5 * 41 so thats a 4 pt DFT followed by a 5 point DFT followed by a 41 point DFT
I think I have to go down the route of adding a custom FPGA acclerator to the SHARC -- which is where my other discussion on using Blackfin FPGA extender with SHARC comes in
