主存储器访问调度技术研究

Research on Memory Access Scheduling

论述了主存储器访问操作中的bank预充电、row激活、column读写的访问调度技术。通过该技术可以缩短主存储器访问时间,从而达到提高主存储器带宽的目的。同时,为研究和评价这种主存储器访问调度策略的性能给出了一种建立仿真实验环境的思路。

A memory access scheduling is discussed in this paper. Memory access includes bank precharge, row activation and column access. The scheduling is aimed at increasing memory bandwidth through decreasing memory access latency. On the same time a way to establish a simulation platform for research and evaluation these kinds of scheduling strategies is described in the final section.
