 Description   

I am testing vx_app_load_test.out  on my TDA4VM board.

When i try vx_app_load_test.out to generate 100% load on C7 , the resulting load is slighly lower ( 85%) , as shown below.

./vx_app_load_test.out 2 100 5

The same issue is seen for MCU2_0 as well

Whereas C66x shows 99% when triggered for 100%
