基于异构多核环境下的核间通信机制设计与实现

摘要

To improve the efficiency of inter core communication in heterogeneous multicore environment and to optimize the performance of the processors,an inter-core communication mechanism for heterogeneous multi-core environment was proposed. The architecture of inter core communication mechanism was summarized,and the specific meaning of session layer and transport layer and its interlayer interaction were clarified.On this basis,aprotocol applied to session layer and transport layer was proposed, and the implementation of communication mechanism was completed according to the protocol.Results of experimental tests on ARM+DSP heterogeneous multi-core platform verify the feasibility and effectiveness of the inter-core communication mechanism.%为改善异构多核环境下核间通信效率,实现处理器性能的最优化,提出一种适用于异构多核环境下的分层结构的核间通信机制.对核间通信机制的体系结构进行概述,阐明会话层、传输层的具体含义及其层间交互关系;在此基础上提出应用于会话层与传输层的协议,依据协议完成通信机制的具体实现.在ARM+DSP异构多核平台上进行实验测试,测试结果表明了该机制的可行性与有效性.
