5X00226G03 I/O接口控制器 Ovation

【产品详情】

由于CPU无法直接控制I/O设备的机械部件，因此I/O设备还要有个电子部件作为CPU和I/O设备机械部件之间的“中介”，用于实现CPU对设备的控制，这个电子部件就是I/O控制器，又称为设备控制器。

I/O控制器是控制计算机输入输出的一个最基本的控制系统，可指挥计算机的各个部件按照指令的功能要求协调工作的部件。它由指令寄存器IR（InstructionRegister）、程序计数器PC（ProgramCounter）和操作控制器OC（OperationController）三个部件组成，对协调整个电脑有序工作极为重要。

【英文介绍】

Since the CPU cannot directly control the mechanical parts of the I/O device, the I/O device also has an electronic part as the "intermediary" between the CPU and the mechanical parts of the I/O device, which is used to achieve the control of the CPU on the device, the electronic part is the I/O controller, also known as the device controller.

The I/O controller is the most basic control system that controls the input and output of the computer, and can direct the various components of the computer to coordinate the work according to the functional requirements of the instruction. It is composed of three parts: instruction register IR (InstructionRegister), program counter PC (ProgramCounter) and operation controller OC (OperationController), which is extremely important to coordinate the orderly work of the whole computer.
