Open msnagar opened 1 year ago

msnagar commented 1 year ago

Dear criss, what is the procedure to calculate the different performance metrics on the GVSOC/GAP_SDK? like load and stall cycles and others.. I want to use HWCE on GAP8 kit is there any sample codes or tutorials with you? then please share... Is there any way to add the custom instructions or accelerator with the simulator?

Thanks and regard

Hello, @msnagar

You can use the performance counters for the GAP8 : https://greenwaves-technologies.com/manuals/BUILD/PMSIS_API/html/groupGAP8PERF.html These allow you to get cycles, cache miss, etc.

Regarding the HWCE on GAP8, indeed, there is no example to use it, and unfortunately, on the official website of the kit, they say that they have an API, but it is not open to use because it has many limitations.

You can check the official response here : GreenWaves-Technologies/gap_sdk/issues/246#issue-943094040

I hope to have helped you.
