dsp processor with a FFT processor

[balasub]

In my project i have a DSP processor and a FFT processor interacting...

What is the need for this FFT processor?
i am new to DSP.

Usually it's either for spectrum analysis (eg, radio astronomy/radar) or
linear filtering/convolution. It is unusual, these days, to have a
dedicated "FFT" processor, as opposed to FFT code running on a
conventional DSP processor, since it's hard for the former to keep up
with the latter. (I started my professional career by coding up a
replacement for an FFT chip on an OTS DSP...) Which FFT processor is it,
by the way?

thanks andrew...
i am not sure of which processor is used.
what are the scenarios to be covered if we need to verify a SOC havin
dsp,gpp and fft
