Hello, Has anyone used the DSP library provided by TI for performing N-point real FFT. It says that when the input is in bit-reversed order, the output of rfft() function gives the results as follows.... Re(y(0)) Im(y(Nyquist)) Re(y(1)) Im(y(1)) and so on........but I was not able to find it. Regards, Santosh *************** Santosh M Nadig Systems Engineer Accord Software & Systems Pvt Ltd.

Hi, the dsplib functions will come with ccs. Go to the directory \ti\c5400\cgtools\dsplib\54x_src. There all functions those are listed in dsplib application manual will be available.
