摘要:
7.3Hardware Prefetching 《Speculative Execution in High Performance Computer Architectures》本节主要介绍硬件数据预取,数据预取分为2个端,处理器端和内存端,处理器端主要在主要在L1或者L2实现预取,内存端主要在内存控制器中实现。预取算法也有3种:顺序或者步长预取(Stride and Sequential Prefetching),关联性预取(Correlation Prefetching),内容关联性预取(Content-Based Prefetching)顺序或者步长预取(Stride and Sequ 阅读全文
