Fredy,
What sort of utilization are you looking for here? Panel utilization or the # cycles the MMA is active in a given window?

Varun:

For example, how do we count the actual computing power used by 8Tops over a period of time?

Fredy,
If the question is around time utilization (i.e. how many cycles the MMA is active) - you can use C7x's timestamp counters (__TSC) to measure cycles taken by your MMA kernel and measure the cycles the MMA is running, you can then compare it with the total cycles you spend on other operations.

Varun
