I am using:
ADSP 21489 EZ Kit Lite, VisualDSP++
CFFTF with 16k points
cfftf(input_r,input_i, temp_r,temp_i, twid_r,twid_i,FFT_SIZE);
Is this function using the FFT accelerator?
I checked the assembly code and the registers, and I cant see any accelerator used.
In the manual they call FFTs with more than 512 points "large", so is my 16k FFT super ultra large () and impossible to calculate with the accelerators?
