Question about efficiency of FFT for multicore 6678

Other Parts Discussed in Thread: TMS320C6678

Hi All,
I use TMS320C6678 and dsplib to calculate of fft. I attempt calculate fft to eight cores simultaneously..My question is how make it optimal? I can create eight independent projects - one per core and synchronize its using semaphores. Or I can create separate memory segment for fft calculating. What is more efficient from the point to run-time?

Best regards,

    Hi Oleg,

    Yes, the optimal method would be to use the semaphore and do a mutual exclusive usage of fft code in a particular memory.
