Hi,
we are operating the M4F with 160MHz and we would like the know the MFLOPS we can achieve with this configuration.

Hi Joseph,
many thanks. Yes, this helps.
Hi TImm,
The instruction timing of the Cortex-M4 with FPU is listed in the Technical Reference Manual:
General instructions:

DSP instructions:

Floating point instructions
http://infocenter.arm.com/help/topic/com.arm.doc.100166_0001_00_en/ric1417175938834.html
From the table you can see most FPU instruction range from 1 to 3 clock cycles (except divide).
Hope this helps.
regards,
Joseph
