嵌入式系统高速缓存一致性优化解决方案

Solution to the Optimization of Data Consistency in Embedded System with CACHE

嵌入式系统多采用高速缓存技术,以提升系统整体性能.阐述了嵌入式系统Cache的一致性问题,结合ARM处理器Cache中出现的数据不一致的情况进行了分析,进而给出了解决此问题的可行性方案,并采用系统软件加以实现.

CACHE is mostly applied to embedded systems in order to improve the performance of system. This paper expatiates on problems about Cache data consistency in most of embedded systems, analyzes the reasons for the data inconsistency problems in ARM processors, presents one optimization solution to these problems, and implements it with system software.
