Power Consumption and Performance’s Library on DSPs: Case Study MPEG2

Jalel Ktari, Mohamed Abid, Nathalie Julien and Johann Laurent


The growing demand for portable electronic devices has led to an increased emphasis on power consumption within the semiconductor industry. As a result, designers are now encouraged to consider the impact of their decisions not only on speed and area, but also on power throughout the design space exploration. This article presents a high-level design space exploration methodology. It allows characterising a software application computing on TI-DSPs. The proposed approach exploits parametric models representing the consumption’s behaviour of both DSP’s architecture and algorithm. This consists in releasing the laws of consumption on a high level. This approach makes it possible to deduce the power and the energy consumption of a code in an advanced language for a given target. Feasibility and the interest of the approach were proved using MPEG2. This new approach was based on a functional level power analysis. The advantage of this approach was that the consumption and performance estimation can be made at a high level. Moreover, the proposed approach gives a detailed function-level characterization of the energy behaviour of application, enabling estimation of software energy consumption.
