面向混合内存体系结构的模拟器

Simulator for hybrid memory architecture

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 architec-ture based on gem5. When building, this method first added a hybrid memory controller betweenthe memory bus and the memory model, then introduced the non-volatile memory model of NV-Main and hooked it up to the the newly added hybrid memory controller along with the nativeDRAM model of gemS. This method could achieve the goal of building a simulator for hybridmemory architecture, which was proved by the experiment results.
