对于不可CACHE的外部内存区域,请求的数据简单地直接由外部内存送到CPU,不会存储在任何CACHE中。 2.2 Write Miss和Hit CPU对外部可CACHE的内存进行写请求,这个数据地址在L1D中Miss,于是通过Write buffer送到L2,如果L2检测到这个地址是Miss,对应的L2 CACHE Line从外部内存取进来,然后更新。LRU位决定哪个Way的Line Fram...
2.L2 CACHE的Miss和Hit 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(...
在执行程序前,首先会试图把要用到的指令、数据从主存移到cache中,然后在执行程序时直接访问cache。如果指令、数据在cache中,那么我们能很快地读取出来,这称为“命中(hit)”;如果指令、数据不在cache中,我们仍旧要从主存中拿指令、数据,这称为“不命中(miss)”。命中率对于cache而言是很重要的。 现代处理器一般有...
