What is the FFT benchmark numbers (in terms of CPU cycles) on Cortex R4F? From the TMS570 CMSIS document
Q15 Q31 F32
CFFT B - 64 3236 5407 2996
CFFT Mag B - 64 10961 14277 4125
RFFT B - 128 4811 7639 4827
DCT B - 128 11066 15948 9256
Does this mean 16 bit 128 point (Q15 format) complex FFT on Cortex R4F takes 11066 cycles?
Thanks
