Cortex-A8将L2 cache带进了处理器内部,并且L2 cache开始使用cache prefetch的功能,虽然还是需要软件控制PLE引擎来实现(后面转换成hardware prefetch). 并且L2 cache 可以独立于L1 cache进行开关。 Cortex-A8的cache line大小也随着总线宽度的提高变成64 bytes. 它之前的CPU的cache line为32 bytes。 在cache方面,在一...

在某些实现中,对于某些内存类型,原子属性只能通过PE之外的功能来满足,一些系统实现可能不支持所有内存区域的原子指令,这尤其适用于:1.不支持硬件cache coherency的任何存储;2.Device,non-cacheable memory,或者被看作是non-cacheable的memory, 第二节 cache and memory hierarchy ...
A second-level cache is a memory component in a computer system that stores data which is not found in the on-chip cache, providing a larger but slower access memory compared to the on-chip cache. AI generated definition based on: Digital Design and Computer Architecture (Second Edition), ...
RocksDB的写缓存(即LSM树的最低一级)名为memtable,对应HBase的MemStore;读缓存名为block cache,对应HBase的同名组件。 执行写操作时,先同时写memtable与预写日志WAL。memtable写满后会自动转换成不可变的(immutable)memtable,并flush到磁盘,形成L0级sstable文件。sstable即有序字符串表(sorted string table),其内...
