FFT/IFFT: 2D Implementation
Introduction[edit]
The fixed point FFT and IFFT functions provided with the C64x+ DSPLIB can be used to implement a 2D FFT->IFFT.
Example Application[edit]
Find attached with this article a CCS v3.3 example project that demonstrates the usage of the 64+ DSPLIB's fixed point DSP_fft32x32() and DSP_ifft32x32() functions to implement a 2D-FFT->2D-IFFT of an NxN 8-bpp grayscale image (where N is a power of 2). In the example N=512.
