DSP56603A Technical Data Sheet

APPENDIX A
POWER CONSUMPTION BENCHMARK
The following benchmark program permits evaluation of DSP power usage in a test situation. It
enables the PLL. Then it disables the XTAL generation, external CLKOUT generation, external
port, and PC-relative instructions. Finally, it uses repeated Multiplier-Accumulator (MAC)
instructions with a set of synthetic DSP application data to emulate intensive sustained DSP
operation.
This synthetic benchmark provides a structure and performance that is similar to a typical DSP-
intensive algorithm, as used in the target cellular subscriber market. A typical target application
consumes approximately 90% of the current used by this benchmark program.
The two listed equate files, ioequ.asm and intequ.asm, are available in print format in
Appendix B
of the DSP56603A Users Manual (DSP56603AUM/AD) as well as electronically via
the Internet on the Motorola DSP home page. The web page address is provided on the back
page of this document.
