This document assists in the estimation of power consumption for TMS320VC5509A digital signal processors (DSPs). Power consumption on these devices is highly application-dependent, so a spreadsheet is provided to model power consumption.

The spreadsheet allows a user to enter parameters that closely resemble the application and generate a realistic estimate of DSP power consumption based on his/her input. It also allows designers the ability to test the efficiency of different configurations before any hardware is assembled or any code is written.
