Power consumption for the C6748/46/42 can vary widely depending on the use of on-chip resources. Thus, power consumption cannot be estimated accurately without an understanding of the components of the System-on-Chip (SoC) in use and the usage patterns for those components. By providing the usage parameters that describe how and what on the SoC is being used, accurate consumption numbers can be obtained for power-supply and thermal analysis.

This model breaks down power consumption into two major components: baseline power and activity power. Using this model, various applications that use the SoC differently can get accurate predictions across the spectrum of possible power consumption on the C6748/46/42.
