RTOS/AM5728: DSP performance problem

Tool/software: TI-RTOS

Hi, kind TI and everyone!

I researched the performance data of AM5728 Cx66 DSP as bellow:

These data has different values.

Q1. At 2nd URL, what means DSP optimized, cycles (per core) DSP baseline wall clock DSP optimized wall clock ARM wall clock? And how can I configure these?

Q2. Please tell me the correct performance value, specially for erode, SobelX/SobelY, GaussBlur (3x3) at Cortex A15 and C66x DSP.

Thanks.

Regards, aither.
