Zoom FFT Algorithm on BF537

I am trying to realize a zoom FFT algorithm using BF537. The process should contain a frequency shift, CIC FIR design, decimation and other array operations. I would like to make full use of the DSP hardware resources to make sure we can achieve the time limit requirements.


I designed a program which consumes at least 5 minutes each calculation process, and I think the problem lies in the array operation and other non-hardware realization.  Do we have any codes on the relevant algorithm, like frequency shift, CIC design or zoom fft?
