This document discusses the power consumption of the Texas Instruments TMS320DM6441 digital media System-on-Chip (DMSoC). Power consumption on the DM6441 device is highly application-dependent, so a spreadsheet is provided to model power consumption for a user’s application. To get good results from the spreadsheet, realistic usage parameters must be entered. The low-core voltage and other power design optimizations allow these devices to operate with industry-leading performance, while maintaining a low power-to-performance ratio.
The data presented in the accompanying spreadsheet was measured from strong units (representative of maximum end of power consumption for production units); no production units will have average power consumption that exceeds the spreadsheet values. Thus, the spreadsheet values may be used for board thermal analysis and power supply design as a maximum long-term average.
The data presented in this document is actual measured power consumption for the TMS320DM6441 silicon revision 2.1 and earlier devices.
