Hi every body, I would like to know how can I calculate or measure the time and number of cycles of the algorithm which I used in CCS with DSK6711? For example what is the time should be taken to get the FFT analysis for input signal with 10-point FFT in CCS? is it the calculation like cfftr2_dit.sa function which is can get from cycles = ((2N) + 23)log2 (N)+6 also for another algorithms how can...
