KISS FFT Performance on MSC8144

Hi,

 

Does 2.45 milliseconds for a single 512 point FFT (32-bit fixed-point, executing on a single core from M3 memory) seem outrageous for the MSC8144ADS ?  I've seen some benchmarks for TI processors indicating ~150 usec.

 

Thanks,

zpyatt

 

edit:  I forgot to mention this is with optimization level 4 for execution speed, and seems to be independent of SmartDSP or C vs. C+++.
