Abstract

Modern embedded systems designers are required to implement efficient multi-functional applications, over portable platforms under strong energy and resources constraints. Automatic tools may help them in challenging such a complex scenario: to develop complex reconfigurable systems while reducing time-to-market. At the same time, automated methodologies can aid them to manage power consumption. Dataflow models of computation, thanks to their modularity, turned out to be extremely useful to these purposes. In this paper, we will demonstrate as they can be used to automatically achieve power management since the earliest stage of the design flow. In particular, we are focussing on the automation of power gating. The methodology has been evaluated on an image processing use case targeting an ASIC 90 nm CMOS technology.
