Currently I am using the chip MPC5745R, the client want us to measure the consumed CPU load per core in real time, how can I accomplish that?

Thank you for your help.

Hi,

You have 2 possibilities:

1. Use performance monitor embedde on micro:

2. Use external tool like Lauterbach Trace or similar tool from other vendors.

Peter
