Power Consumption Benchmark
The following benchmark program permits evaluation of DSP power usage 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.
