摘　　要：介绍一种基于硬件的、可编程的外存页面重映射机制,它可以明显地改善性能,并且由于减少了外存总线的访问而降低了功耗。另外还提出了一种把应用数据与指令存储器映射到外存页面的高效算法,使用图着色技术来支配页面映射程序,目标是通过把冲突页面重映射到不同的存储体来避免页面缺失。This paper presented a hardware-based, programmable external memory page remapping mechanism which could significantly improve performance and decrease the power budget due to external memory bus accesses. Also developed an efficient algorithm to map application data and instruction memory into external memoir＇ pages. Employed graph-coloring techniques to guide the page mapping procedure. The objective is to avoid page misses by remapping conflicting pages to different memory banks.
