Measuring CPU utlization

VIVEK Gopalakrishnan

Hello,

I wish to measure the CPU utlization for a cortex processor running an RTOS (keil RTX). Without an RTOS, i can measure the idle time to come to some conclusion. But with RTOS, can someone guide me how to measure CPU utlization?

Thanks & Best Regards
Vivek

    This is the internal way of doing the same thing I suggested.

    For the external way - toggling a port pin - it is possible to connect the port pin to a counter input on another processor - such as a eval board - and have it present the CPU load on a display. A very quick hack with a spare Keil eval board and a blinky/hello world app is enough to get a CPU load meter.
