Abstract
This paper describes how profile-driven data compression, a very effective approach to reduce memory and bus traffic in singletask embedded systems, can be extended to the case of systems offering multi-function services. Application-specific profiling is replaced by static data characterization, which allows to cover a larger spectrum of the system’s input space; characterization is performed by either averaging several profiling runs over different application mixes, or by resorting to statistical techniques. Results concerning memory traffic show reductions ranging from 10% to 22%, depending on the adopted data characterization technique.
