基于主存访问相关解决等技术的高带宽主存控制器设计

The Design of Main Memory Controller for High Bandwidth Based on Memory Disambiguation,Memory Reference Scheduling and Address Remapping

随着现代处理器和缓存技术的发展,当代计算机系统的性能日益受到主存系统的制约,对主存带宽的需求将越来越大。论文提出主存访问相关解决、主存访问动态调度和地址重映射三项技术,利用主存访问自身的特性(局部性)、同步DRAM自身的物理特性(操作的并行性)和二者之间的关系(地址映射),设计了新型、高带宽主存控制器,有效地提高了主存系统的带宽。

The performance of modern computer system has been hindered by the memory system ever more.With the development of modern processor and cache technology,there is increasing need of the bandwidth of main memory.The paper gives a comprehensive description of design of main memory controller towards weakness lying in the relative technology.The three techniques employed in the design-memory disambiguation,memory reference scheduling and ad-dress remapping are put forward by the author.By exploiting locality existing in memory references,taking advantage of3-D structure of Synchronous DRAM and the interaction between the two things above,the paper proposed a sophisti-cated design to effectively increase main memory bandwidth.
