面向多任务密码处理的多核核间通信单元设计与研究

摘要

为了解决面向多任务密码处理的多核核间通信机制的优化实现问题，设计一种混合通信机制。在分析多核处理架构及核间通信特点的基础上，融合了簇内共享存储通信和簇间 NoC 通信机制，同时引入了 DMA 通信机制，提出构建混合通信机制，进一步提升通信效率。其次，给出核间通信同步机制的优化实现，解决了同步和存储一致性冲突问题。最后，基于 Design Complier 对设计方案进行了实验评估。实验结果表明，相比其他方案，该方案具有较小的资源代价和较高的性能指标，获得了满意的通信吞吐率。%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.
