可重构处理器中Mini-Cache的设计

合理利用Mini-Cache可以提高系统性能并降低功耗。在IntelXScale和StrongARM处理器中都采用了Mini-Cache技术。很多关于通过编译器及其它方法更好地使用Mini-Cache的研究正在进行。但目前对可重构处理器中利用FPGA片内资源设计Mini-Cache的研究为数不多。本文主要介绍了利用分布在FPGA可配置逻辑块中的DistributedRAM设计Mini-Cache的方法,该方法对于其它类型的RAM资源也同样适用。

Designing Mini-Caches for Reconfigurable Processors

Mini-Cache is an effective means to improve the performance of a system and degrade its power consumption at the same time, which has been implemented in Intel XScale, Strong ARM and other processors. Some researches about how to utilize the Mini-Cache more effectively are ongoing, but few methods about fabricating Mini-Cache in reconfigurable processors based FPGA are proposed now. This paper proposes a method to design a Mini-Cache using the RAM distributed in the CLB, which is applicable for other RAM in the same way.
