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

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.

Joseph
