Abstract

Power and energy dissipation are currently critical design constraints in Digital and Signal Processing (DSP) applications for embedded software ; the increasing weight of the software implies that software consumption mut also be controlled. Moreover, the software dissipation is highly dependant of the processor architecture where the code has to be executed. To guide efficiently the required optimisation all over the design flow, reliable estimations are necessary. We present here an ovrview of the main current estimation techniques, the models they are relying on, their characteristics and applications domains, their respective advantages and drawbacks and eventually the available tools.
