Appendix A 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 instructions with a set of
synthetic DSP application data to emulate intensive sustained DSP operation.
