Description/Abstract

A co-synthesis methodology for design of energy-efficient multi-mode embedded systems is presented. The third part of this thesis concentrates on energy minimisation of emerging distributed embedded systems that accommodate several different application within a single device, i.e., multi-mode embedded systems. A new co-synthesis technique for multi-mode embedded systems based on a novel operational-mode-state-machine specification is presented. The technique increases significantly the energy savings by considering of mode execution probabilities that yields better resource sharing opportunities. The capability of LOPOCOS in efficiently exploring the architectural design space is demonstrated through a system-level design of a realistic smart phone example that integrates a GSM cellular phone transcoder, an MP3 decoder, as well as a JPEG image encoder and decoder.
