hi there, i am rather new to code composer studio V2. i want to calculate the fft of an array. i saw that there were some C-callable functions in dsplib and tried to use the same. there were two problems: 1) cbrev does not seem to be working fine. i had to write my own code for bit reversal. 2) the rfft function's result does not seem to match with matlab when the input data to both is the same. if anyone could show a way out, i would be very greatful Sivaram |

Hi Sivaram, Maybe you haven't aligned the memory as the manual describes.
