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…

Memory Layout (Virtual address space of a C process) 分类: C语言基础2012-12-06 23:16 2174人阅读 评论(0) 收藏 举报 found a good example to demostrate the memory layout and its stack info of a user-mode process, only that this example is for Linux. But it is still wo…

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…

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…

墙外通道:http://thinkiii.blogspot.com/2014/02/arm64-linux-kernel-virtual-address-space.html Now let's talk about the Linux kernel virtual address space on 64-bit ARM CPU. You can find information about ARMv8 in ARM official website. http://www.arm.com/pr…

http://thinkiii.blogspot.jp/2014/02/arm32-linux-kernel-virtual-address-space.html   The 32-bit ARM CPU can address up to 2^32 = 4GB address*. It's not big enough in present days, since the size of available DRAM on computing devices is growing fast a…

转自 http://www.ha97.com/4337.html PS:前天有童鞋问我,为啥我的Linux系统没运行多少程序,显示的可用内存这么少?其实Linux与Win的内存管理不同,会尽量缓存内存以提高读写性能,通常叫做Cache Memory. 有时候你会发现没有什么程序在运行,但是使用top或free命令看到可用内存free项会很少,此时查看系统的 /proc/meminfo 文件,会发现有一项 Cached Memory: 输入cat /proc/meminfo查看:MemTotal:…

1.Unable to handle kernel paging request at virtual address 00000000 =====>越出内核地址空间范围,原因是由于使用空NULL指针 2.Unable to handle kernel paging request at virtual address 20100110 =====>越出内核地址空间范围,原因是的内存越界导致该指针 所在内存被破坏了. 接下来的困难是在什么地方这个内存被修改?为什么被修改? 3.Unable t…

今天在编译好内核模块后,安装内核模块memdev.ko的时候,出现了Unable to handle kernel NULL pointer dereference at virtual address 00000000等如图所示的问题: 在百度和google找了很多答案,明显就是跟指针有关系...访问了空指针什么的... 可是代码也有一些怎么找呢?? 于是我想了一个办法,加入打印语句帮助我知道到底哪个函数出了问题! 果然,一下就找到了,如图: 于是,问题就迎刃而解了... 启发链接: http…
