paging:把待处理信息在主存和硬盘之间来回倒,制造虚拟内存。 scheduler,dispatcher Getting It Started 开机过程 开启前操作系统存储在硬盘中,主存是空的 每次启动,CPU的program counter(存储这下一条指令的地址),都包含一个预定的地址 这个地址指向内存中特殊的ROM(read only memory,掉电依然保存),存储着boot loader ...
instruction register:存储当前执行的指令 program counter:存储下一条指令的地址 machine cycles三步骤: fetch:根据program counter地址从memory中载入指令,放入instruction register;program counter增2字节 decode:根据instruction register中指令的op-code进行解读 execute:激活电路执行指令 An Example of Program Execution P...
In this tutorial, we’ll discuss two components that control the execution of the instructions in a computer: program counter and instruction register. We’ll talk about the importance of the program counter and instruction register. Finally, we’ll explore the core differences between them. 2. ...
