We introduce here a high level power estimation method; the power consumption of a whole algorithm is evaluated at a behavioral level instead of the classical study conducted at the instruction level. We present non exhaustive results on the energy models elaborated for a Texas Instruments DSP. This original energy estimation method has been applied to a classical algorithm (FIR) and validated by measurements; promising results provide an error of less than 8% .
