CMSIS DSP RFFT - too much cycles

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...

Too much or too less stack size

Hi, I've had a question some time ago, because I thought the compiler generates wrong code. Your answers told me that my startup-configuration seems to be wrong. Here I want to say thank you for the...

Cortex-m4 mass storage implementation is too much slow compared to cortex-M3

Hi all, I'm developing on at91SAM3S/4s. I have 2 keil projects sharing the same source code since the 2 core are similar. The base of my project is USB mass storage sample from keil 4.7 for sam3s...
