2.5. Energy-Aware Software

Although employing energy-efficient circuit/architecture techniques is a must for energy-aware MPSoCs, there are also important roles for the software to play. Perhaps one of the most important of these is to parallelize a given application across on-chip processors. It is to be noted that, in this context, it may not be acceptable to use a conventional application parallelization strategy from the high-end computing domain since such strategies focus only on performance and do not account for the energy behavior of the optimized code. More specifically, such high-end computing-oriented techniques can be very extravagant in their use of processors (or machine resources in general), i.e., they tend to use a large number ...
