TMS320VC5503/VC5506/VC5507/C5509A Power Consumption Summary (Rev. C)

This document assists in the estimation of power consumption for the TMS320VC5503/C5506/C5507/C5509A 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 you to enter parameters that closely resemble the application and generate a realistic estimate of DSP power consumption based on your input. It also allows designers the ability to test the efficiency of different configurations before any hardware is assembled or any code is written.

The spreadsheet discussed in this application report can be downloaded from the following URL: http://www-s.ti.com/sc/techlit/spraa04.zip. Although this spreadsheet was developed for the C5509A device, it can be used to model power consumption on the C5503, C5506, and C5507. Features not supported on these devices should not be enabled in the spreadsheet.
