I need to benchmark some C++ code on the FVP_MPS2_Cortex-M4 simulator.
I considered using CMSIS function osKernelGetTickCount() to provide timestamps but the resolution of the tick timer seems to be 1ms, which is too coarse.
What would be a suitable clock counter to use for the timings?
Would ARM_CM_DWT_CYCCNT be suitable and, if so, how would I access it?Best regards

Hi Toshi and Ronan
Thanks for your replies. It's pretty clear that FVP and fast models aren't suitable for my purposes. Does ARM offer a cycle accurate simulator for Cortex-M4? I realise it may be slow but we could tolerate that. If so, could you please tell me where I can obtain it?
Best regards
I've started a new thread 'Cycle accurate simulator for Cortex-M4?' as this one seems to have run its course.
