An optimized method of memory simulation accuracy in multicore multithread processor

摘要

As memory accesses become slower with respect to the processor and consume more power with increasing memory size, the focus of memory performance and power consumption has become increasingly important especially in Multicore-Multithread processor. Multi2Sim is a kind of computer architecture simulation and modeling tool which support Multicore-Multithread processor simulate[4]. The feature makes it a suitable tool for the research of the CMPs architecture. The source code of Multi2Sim is open, which makes it easy to modify and port. But the Multi2Sim provided a poor accuracy to memory system simulation. In this paper, we presented the Multi2Sim simulation framework and make a deep analysis for the key modules kernel. According to the defect, we introduced a project that integrate the DRAMsim with Multi2Sim to solve the problem and gain a accurate memory simulation. At last we discussed the performance of the project.
