A method for managing a memory, including obtaining a number of indices and a cache line size of a cache memory, computing a cache page size by multiplying the number of indices by the cache line size, calculating a greatest common denominator (GCD)…

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…

Delphi之静态方法,虚方法virtual,动态dynamic,抽象abstract,消息 http://www.cnblogs.com/zhwx/archive/2012/08/28/2660555.html 对象的方法能定义成静态(static).虚拟(virtual).动态(dynamic)或消息处理(message).请看下面 的例子: TFoo = class procedure IAmAStatic; procedure IAmAVirtual; virtual; procedur…

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…

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…

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…

1.overload 在Pascal语法规则中,同一个UNIT里是不能存在两个同名的函数的,例如: function func(): Boolean; function func(const x: Char): Boolean; 这样是会出语法错误的,原因是因为标识符规则限制.但是问题出来了,如果我们需要几个功能相似但是参数不同的函数,那么根据标识符规则,我们就必须定义几个不同名,但是功能相同或相似的函数.    如,假设我需要一个函数,要实现返回参数一减去参数二后的值,那么我们就将这样定义函数…
