多粒度通信优化的MPSoC调度映射策略
MPSoC mapping and scheduling approach with multi-grained communication optimizations
摘要
Abstract
As the number of processors in an embedded system increases, mapping and scheduling become key challenges of system software designers.To achieve high performance, communication overheads should be addressed during mapping and scheduling process.Most existing mapping and scheduling approaches exploit coarse-grained system level communication optimizations from a global view, and standalone communication optimization techniques adopt fine-grained thread level communication optimizations from a local view.While these communication optimization techniques can improve performance, they still face problems.In this work, an integer linear programming (ILP)-based mapping and scheduling approach is proposed with multi-grained communication optimizations for Simulink models, which can efficiently exploit the advantages of different granularities of communication optimizations and complement their disadvantages.It conducts coarse-grained communication optimization during the mapping process and fine-grained communication optimization during the scheduling process.Experimental results show that the proposed approach can improve the overall system performance significantly.关键词
