In a particular embodiment, a circuit device includes a translation look-aside buffer (TLB) configured to receive a virtual address and to translate the virtual address to a physical address of a cache having at least two partitions. The circuit devi
cache释放: To free pagecache: > /proc/sys/vm/drop_caches To free dentries and inodes: > /proc/sys/vm/drop_caches To free pagecache, dentries and inodes: > /proc/sys/vm/drop_caches 说明,释放前最好sync一下,防止丢数据. 附: linux cache内存释放bash 脚本 #! /bin/sh freemem=$
在free命令中有个参数l,它表示 show detailed low and high memory statistics.其实最先是对High Memory总是为零有些不解(Linux是64为).其实更不解的是关于low memory.high memory.那么关于low memory和high memory是怎么一回事呢?如下截图所示: 一直对这个概念不解,直到看到关于linux kernel里的high memory 这篇文章.下面文字全部摘自这篇文章: 今天有人问我linux ker
An embodiment provides a virtual address cache memory including: a TLB virtual page memory configured to, when a rewrite to a TLB occurs, rewrite entry data; a data memory configured to hold cache data using a virtual page tag or a page offset as a c
Methods and apparatus to provide for power consumption reduction in memories (such as cache memories) are described. In one embodiment, a virtual tag is used to determine whether to access a cache way. The virtual tag access and comparison may be per
