多核密码处理器数据缓存机制研究

Research on Data Buffer Mechanism of MCP

摘要: 对多核密码处理器的数据缓存特点进行了研究, 提出了一种基于双RAM与硬件队列的多核密码处理器数据缓存机制, 并设计了相应的多核数据分配控制器.最后与现有的数据缓存方式在多核密码处理器中的应用性能进行了对比, 结果证明提出的多核数据缓存机制具有更高的吞吐率与核心利用率, 从而提高了多核密码处理性能.

Abstract: This paper researched the data buffer feature of MCP and proposed a data buffer mechanism based on couple RAM and circuit-queue. Then this paper designed a data buffer controller. At last, different schemes of MCP data buffering are compared. The result shows that the mechanism proposed in this paper has higher throughput rate and higher core use ratio.
