CPU 在进行 load/store 时，会使用虚拟地址，需要在访问时转换成物理地址。对于 L1 Cache，一般有两种实施方式： 1. VIPT (virtual index physical tag)：使用虚拟地址查 index，用物理地址匹配 tag，这样虚拟地址->物理地址 … Zobacz więcej Cache 的组织结构一般如下图： Cache 主要由两块组成：tag array 和 data array data array 由多个 set 构成（一些教材将 set 中文译为 … Zobacz więcej 阻塞式 cache (blocking cache)：流水线访问 cache 发生 miss 时，流水线发生阻塞，直到数据从下级访存系统中获取到后再恢复执行。阻塞式 cache 的好处是简单，但是一旦发生阻塞，会严重拖慢流水线性能。 非阻塞式 cache … Zobacz więcej 最近翻到了一篇绝佳的文献：Processor Microarchitecture: An Implementation Perspective，是 Antonio González, Fernando Latorre, and Grigorios Magklis 等人于 2011 年 … Zobacz więcej 一般架构有 1~3 级 Cache。 1. L1 Cache 一般相联度 ( associativity ) 较低（减少延迟、提高吞吐），容量为几十 KB 左右，延迟一般为 1~4 Cycle，且往往被分成 ICache 和 DCache，一般 L1 Cache 是由一个 CPU 核心 … Zobacz więcej WitrynaRegisters (MSHRs) [8], and the number of MSHRs determine the number of outstanding misses a cache can have before it blocks. This number is closely related to the notion of ... An improvement over the implicitly addressed method is the explicitly addressed MSHR field design. Here, the address within the block is explicitly stored in the … Witrynaas for example the width of the load, byte address for byte addressed loads and if the data should be sign extended.
