Abstract
In order to solve the problem of optimising implementation in regard to multi-task cipher processing-oriented inter-core commu-nication mechanism for multiple cores,we designed a mixed communication mechanism.Based on analysing the multi-core processing architec-ture and the characteristic of inter-core communication,in this paper we first propose to construct the mixed communication mechanism by in-tegrating the communication mechanism of shared-memory within clusters and the message passing mechanism among clusters meanwhile intro-ducing the direct memory access (DMA)communication mechanism,and this further improves the communication efficiency.Secondly,we present the optimising implementation of inter-core communication synchronisation mechanism and this solves the problem of consistency con-flict in synchronisation and storage.Finally,we evaluate the design scheme through experiment based on Design Complier.Experimental results show that the scheme has less resource cost and higher performance indicators compared with other schemes,and achieves satisfied communi-cation throughput as well.关键词
