Hardware/software support for adaptive work-stealing in on-chip multiprocessor

During the past few years, embedded digital systems have been requested to provide a huge amount of processing power and functionality. A very likely foreseeable step to pursue this computational and flexibility trend is the generalization of on chip multiprocessor platforms (MPSoC). In that context, choosing a programming model and providing optimized hardware support to it on these platforms is a challenging task. To deal in a portable way with MPSoCs having a different number of processors running possibly at different frequencies, Work Stealing (WS) based parallelization is a current research trend. The contribution of this paper is to evaluate the impact of some simple MPSoCs' architecture characteristics on the performance of WS in the MPSoC context. The previous evaluations of WS, either theoretical or experimental, were done on fixed multicores architectures. This work extends these studies by exploring the use of WS for the codesign of embedded applications on MPSoC plat...
