Compiler/AM5706: Benchmarks on AM5706 running on the C6xxx DSP not optimal

Blake Carpenter

Part Number: AM5706

Tool/software: TI C/C++ Compiler

Hi,

I am running into a problem with executing benchmarks on the AM57 DSP. The code compiles and runs correctly, but I feel I am getting a fraction of the performance I should be getting. I suspect my compiler is not properly set up for optimizing my code. The competing solution on an A9 is running much faster, which in theory should not be the case.

Unfortunately I am not sure what switches to flip or where to find them.

Can you help? I am hoiping to get 32 MAC's per cycle, but it appears that is not happening.

Best Regards, Blake

Please try the suggestions in the wiki articles C6000 Compiler: Recommended Compiler Options and C6000 Compiler: Tuning Software Pipelined Loops. If that doesn't work, then we need a test case. To submit a test case, please:

Preprocess the source code with the benchmarks
Attach that to your next post
Indicate the name of the function(s) to optimize
Show the compiler (not CCS) version
Show the build options exactly as the compiler sees them

Thanks and regards,

-George
