CPU Idle time estimation

Added by Marco Cini 6 months ago

Hi,
is there a way to evaluate the CPU idle time using some of the blocks present in WJ2?
Since FreeRTOS is used, is it possible to call dedicated functions to output directly the CPU Idle task?

Thank you in advance,
Marco Cini

Could anyone help me with this?

Hi Marco,

Currently, there is no option to measure the CPU idle time using Waijung 2 blockset. But you can do a Code execution profiling using PIL (Processor in the loop (PIL) simulation) to get an idea about the execution cycle. Using PIL, you can generate a code execution profiling report regarding the CPU utilization and execution cycle in detail. I hope this will help you for evaluating the CPU idle time.

There are some limitations related to PIL,

Waijung 2 only supports PIL using Model Block
Other related limitations: https://www.mathworks.com/help/ecoder/ug/sil-and-pil-simulation-limitations.html

Best regards,
Chandima
