2.2 Processor Core Utilization

This section allows users to load each compute core with utilization between 0%-100% (inclusive). For guidance, 0% is an off or unused state. 1% is idle. 100% is maximum utilization (that is, Dhrystone).

For the C7x DSP there is no mode to toggle MMA usage or not. Because of this, TI recommends that, if MMA is not used, then the valid range of % Utilization is 0 to 50%. For example, if the customer intends to model 100% activity without MMA usage, then 50% is the appropriate value. When MMA of the DSP is used, the valid range is 0 to 100%.
