8851-LC-MT控制器是指按照预定顺序改变主电路或控制电路的接线和改变电路中电阻值来控制电动机的启动、调速、制动和反向的主令装置。

控制器由程序计数器、指令寄存器、指令译码器、时序产生器和操作控制器组成，它是发布命令的"决策机构"，即完成协调和指挥整个计算机系统的操作。

8851-LC-MT控制器的基本功能与工作原理是什么

控制器的基本功能是从主存中取出一条指令并指出下一条指令在主存中的位置，对指令进行译码或测试产生相应的操作控制信号以启动规定的动作，指挥并控制CPU、主存、输入和输出设备之间的数据流动方向。

控制器的工作原理是，根据指令的要求、当前的时序及外部和内部的状态，按时间的顺序发送一系列微操作控制信号。

The 8851-LC-MT controller is a master device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor in accordance with the predetermined sequence.

The controller is composed of program counter, instruction register, instruction decoder, timing generator and operation controller. It is a "decision mechanism" that issues commands, that is, to complete the coordination and command of the operation of the whole computer system.

What is the basic function and working principle of the 8851-LC-MT controller

The basic function of the controller is to take out an instruction from the main memory and point out the position of the next instruction in the main memory, decode or test the instruction to generate the corresponding operation control signal to start the specified action, command and control the data flow direction between the CPU, main memory, input and output devices.

The working principle of the controller is to send a series of microoperating control signals in the order of time according to the requirements of the instruction, the current timing and the external and internal states.
