提出了一种基于全系统模拟器gem5的混合内存系统模拟器的构建方法.构建混合内存系统模拟器时，首先在gemg5中添加一层混合内存控制器结构，然后引入NVMain中的新型非易失性内存模型与gem5原生DRAM内存模型一起挂接到新添加的混合内存控制器上.实验结果表明，该方法能够实现构建混合内存系统模拟器的目标.

This paper proposed a method for building a simulator for hybrid memory architecture based on gem5. When building, this method first added a hybrid memory controller between the memory bus and the memory model, then introduced the nonvolatile memory model of NVMain and hooked it up to the the newly added hybrid memory controller along with the native DRAM model of gem5. This method could achieve the goal of building a simulator for hybrid memory architecture, which was proved by the experiment results.
