Hi,
I use the CMSIS DSP library to calculate a f32 RFFT with a block size of 1024. For this it takes 262823 cycles. I read in the white-paper that it should take 55538 cycles. Because of the measurement is too slow, i have to speed it up. What could be the reason of the too much cycles?
Thanks
My setup: Cortex-M4 on a TI-MSP432 TI-Code Composer Studio wait states = 0 function: arm_rfft_fast_f32()
