Computer Science An Overview _J. Glenn Brookshear _11th Edition We have already encountered the concept of a pointer in our study of CPUs in Chapter 2. There we found that a register called a program counter is used to hold the address of the next in…

几个重要的 Win32 寄存器 EIP 指令寄存器(Extended Instruction Pointer) 存放一个指针,指向下一条等待执行的指令地址 ESP 栈指针寄存器(Extended Stack Pointer) 存放一个指针,指向系统栈最上面栈帧的栈顶 EBP 基址指针寄存器(Extended Base Pointer) 存放一个指针,指向系统栈最上面栈帧的底部 函数栈帧 ESP 与 EBP 之间的空间为当前函数的栈帧.函数栈帧一般包含:局部变量,栈帧状态值(前栈帧的底部),返回地…

A data processor (104) is described. The data processor (104) is capable of decoding and executing a first instruction (212) of a first instruction set and a second instruction (213-219) in a second instruction set wherein the first instruction (212)…

BACKGROUND OF THE INVENTION A conventional virtual-machine monitor (VMM) typically runs on a computer and presents to other software the abstraction of one or more virtual machines. Each virtual machine may function as a self-contained platform, runn…
