As I read the FFTC document I come across the PING PONG buffer .

I also want to know how to access that buffer and what is the size of that buffer ?

Is it present within the FFT co-processor or any other memory is being used for this ?

Merged threads. I'll ping someone to take a look at this.

Each FFT Co-processor has only ONE FFT Engine.

With regard to buffers, the ping-pong buffers referred to are internal buffers used by the engine that cannot be access by the user. In fact there are three internal buffers. Refer to section 2.1.2 (FFT Engine) of the FFTC users guide for a description of these buffers.

The application still has to allocate system memory to hold input and output data. Refer to the "Multi-core Navigator" users guide for more information.
