The increasing demand for portable computing has elevated power consumption to be one of the most critical embedded systems design parameters. In this paper, the authors present a precise high-level power estimation methodology for the software loaded on a VLIW processor that is based on a functional level power model. The targeted processor of their approach is the TMS320C6416T DSP from Texas Instrument. The contributions are the following; a precise model to estimate the power consumption of the targeted DSP, while running a software algorithm is proposed, they prove the validation and precision of their model on many typical algorithms applied in signal and image processing and they further validate the precision of their model on a real application applied in the video processing field.
