【摘要】：与不断提升的计算能力相适应,移动手持设备上的存储系统结构越来越复杂,容量越来越大.这种趋势导致存储系统,主要是片上缓存和主存,在系统总能耗的占比中不断攀升.在当前手持设备多由电池驱动并且电池容量十分有限的情况下,存储系统的低功耗设计就显得十分重要.虽然现有的存储器件提供了一定的硬件节能支持,但是只有与应用程序的访存行为的规律相结合,才能充分发挥硬件的节能潜力.对现有的各种低功耗存储技术进行了梳理和总结,给出程序的访存模式的概念,归纳出访存模式在3个方面的内涵,并进一步详细介绍了程序的访存模式在片上缓存和主存低功耗技术中的应用.最后,展望未来结合访存模式进行低功耗存储系统研发的可能方向.
[Abstract]:With the increasing computing power, the structure of storage system on mobile handheld devices is becoming more and more complex and the capacity is increasing. This trend leads storage systems, mainly on-chip caching and main memory, to increase in the proportion of total system energy consumption. Under the condition that most handheld devices are driven by battery and the battery capacity is very limited, it is very important to design the low power consumption of storage system. Although the existing memory devices provide a certain degree of hardware energy saving support, only when combined with the rules of memory access behavior of applications, can the energy saving potential of hardware be fully brought into full play. In this paper, the current low power storage technology is summarized, the concept of program memory access mode is given, and the connotation of visiting memory mode in three aspects is summarized. Furthermore, the application of program memory access mode in on-chip cache and main memory low power technology is introduced in detail. Finally, the possible direction of low power storage system research and development combined with memory access mode in the future is prospected.
