Webother words, column i of fXis the FFT of column i of X. 2. For each row of fX, compute its FFT. Call the m-by-n array of row FFTs ffX.In other words, row i of ffXis the FFT of row i of fX. ffXis called the 2-dimensional FFT of X. We use ffX for compression as follows. The motivation is similar to what we saw before, 4 WebChisel-FFT. NOTE: The branch BRAM contains codes using BRAM explicitely in FPGA flow.
