摘　　要：为了提高多任务密码算法硬件实现的高效性,对密码算法的多核处理特征及多核互连结构设计基本定律——Amdahl定律进行了研究,提出了密码多核处理器的结构模型,并针对影响多核系统处理性能的参数进行了模拟及分析。基于分析结果,对通用多核处理器中常用的2D-Mesh互联结构进行了优化设计,并给出了优化方案的硬件实现。最后基于VCS仿真平台对设计方案进行了仿真验证。验证结果表明,相比于传统2D-Mesh结构,本方案具有较低的核间信息传递延迟,证明了改进方案的合理性。In order to improve the efficiency of implementing processing and the basic law about the multi-core connective multi-task cryptographic algorithms, the characteristic of multi-core structure the law of Amdahl is analyzed in this paper. Then the structure model of multi-core processing is proposed, and the simulation and analysis of the parameters on affecting the performance of multi-core processing is implemented. The improced connective structure of 2D-Mesh and the implementation are provided based on the result. Finally the work efficiency of the improved scheme is verified by the simulation tool of VCS. The result shows that the plan can effectively accelerate the speed of message passing in multi-core system compared to the conventional structure of 2D-Mesh, proving the rationality of the improvement programs.
