The power estimation spreadsheet provides power consumption estimates based on measured and simulated data; they are provided “as is” and are not ensured within a specified precision. Power consumption depends on electrical parameters, silicon process variations, environmental conditions, and use cases running on the processor during operation. Actual power consumption should be verified in the real system. This tool is meant for estimating power consumption during realistic operating modes; it is not intended for power supply sizing. This power estimation spreadsheet is preliminary and subject to change. This spreadsheet can be downloaded from the web at: https://www.ti.com/lit/zip/SPRR464.

The input part of the spreadsheet consists of following 3 sections: Processing Elements, Interfaces and Power Report.
To use the input part the spreadsheet, users must modify the fields with their appropriate usage parameters. Cells designed for user input are in Yellow. Fields that cannot be modified are Gray. Fields in blue are the output calculated power. Configure the yellow cells to a value most closely aligned with your intended scenario.
The purpose of each of these sections is:
