TDA2EXEVM: Profiling algorithm on EVE in SYS/BIOS task function

Manavi H V

Part Number: TDA2EXEVM

Hi,

I'm running the algorithm on EVE core in task function of SYS/BIOS and checking the profiling time.

problem here is, I can see the performance improves when I run the same algorithm in main function and performance degrades if I run the algorithm in SYS/BIOS task function. Please let us know how the performance is affecting when we run the algorithm in task function.

One thig we observed that in main function we used DMEM as stack region and in task function it uses task local stack. how to move task local stack of SYS/BIOS task to DMEM or EVE internal memory.

Hi Manavi,

Yes, it is recommended to use internal memory DMEM for the stack. I think this is also what is done in the stack.

For moving stack, you would just need to modify the linker command file for EVE. Can you please refer to this file in the vision sdk and try moving stack to DMEM memory?

Hi Brijesh,

Thank you for the suggestion. We are able to achieve the performance after creating task statically.
