看来“under”可以解释为“after”或“follow”,意思是前面的访问是未命中,而后续的访问是命中。这种理解正确吗?如果,我想知道使用“下面”这个词是否有特殊的上下文(即使用空间关系而不是时间关系)。 pax*_*blo5 在这种情况下,“under”一词可能意味着“期间”或“同时”,如“在(从先前的未命中中恢复的情况下...
1. A cache memory control circuit operable to control a cache memory in the case where a cache miss occurs for a first move-in request that precedes a second move-in request to a cache memory and a move-in buffer (17) is being acquired, comprising: a first determination section (41) ...
Miss-under-miss processing and cache flushing Described herein are systems and methods that reduce the latency which may occur when a level one (L1) cache issues a request to a level two (L2) cache, and that ensure that a translation requests sent to an L2 cache are flushed during a......
Method for cache hit under miss collision handling
cpu对一个可cache的外部内存产生读请求如果在l1可能是l1p或l1d发生miss再如果这个地址在l2cache中也miss那么对应行被读入到l2cachelru位决定哪个way的lineframe被定位取代如果这个lineframe包含dirty数据它首先在新的行去进来之前被writeback到外部内存如果这个line也包含在l1d中则l1d中的这个line首先在l2这一行送到...
1.L1 CACHE的Miss和Hit 1.1 Read Miss 见2.1。 1.2 Write Miss L1D是Read-allocate CACHE,意味着仅在发生Read Miss时才会读入新的行。如果写Miss发生,数据通过一个Write Buffer写到低一级内存,从而把L1D CACHE旁路。写buffer包含4个entries,每个entry是64位宽。

While caching is one of the most vital mechanisms for improving site performance, frequent cache misses will increase data access time, resulting in a poor user experience and high bounce rates.This article will help you better understand what a cache miss is, how cache misses work, and how ...
网络中的数据;命中;下的命中 网络释义
No Write Allocate: CPU Write data to Main Memory, but No Allocate it in Cache. Read/Write在Hit/Miss情况下,不同策略的表现行为: 行为 2. Write策略组合 不同Write Hit和Write MIss策略组合下的行为: 所以常见的组合是Write Through-No Write Allocate和Write Back-Write Allocate。
