Power Consumption Benchmark
The following benchmark program evaluates DSP56321 power use in a test situation. It enables the PLL, disables
the external clock, and uses repeated multiply-accumulate (MAC) instructions with a set of synthetic DSP
application data to emulate intensive sustained DSP operation.
