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) ...
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...
Address translations for subsequent commands depending from the command getting the miss may be preserved until the address translation entry is retrieved from memory. Therefore, retranslation of addresses for subsequent commands is avoided.John D. Irish...
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......
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。

2.1 Read Miss和Hit 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L2 CACHE中也Miss,那么对应行被读入到L2 CACHE。LRU位决定哪个Way的Line Frame被定位取代,如果这个Line Frame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...

Anything over 95% is an excellent hit ratio. That said, check the cache configuration if it’s under 80%. While tracking the cache hit ratio is essential for every website, manually calculating the value is not the best alternative. Thanks to caching plugins like LiteSpeed Cache, WP Rocket...
