eZDSP FFT Hardware Accelerator Documentation

Hi Abhishek,

We have not released the FFT documentation yet but are very close to releasing it.  It should be released in the first half of April and I will post an update here once it is done.  If you would like a preliminary copy can you please contact your TI representative and ask them to check with me.

Best regards, Vishal

Hi Vishal,

I've been woriking on a project which includes the hardware fft on a tms320vc5505 ezdsp, I downloaded the example code from the google page. I try the code with CCS and the debugger and all worked fine, but when i tried to use it stand alone the program doesn't run and it seems like hardware fft is too slow to process the input data from the audio codec.

I'm guessing i need to include some kind of additional configuration, to make the stand alone run like the CCS debug session.

It would be very helpfull if you already have the documentation about the hardware fft, or if can provide me with some meaningful information about this.

Thanks.... Edgar

Hi Edgar,

Can you post the url of FFT example code.

Hi Abhishek,
