APPENDIX E
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.
