UNS2882A 3BHE003855R0001 Controller consists of program counter, instruction register, instruction decoder controller is composed of what
The controller is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller.
The controller is divided into combinatorial logic controller and microprogram controller. The two controllers have their own advantages and disadvantages. Combinatorial logic controller design is troublesome, complex structure, once the design is completed, it can not be modified or expanded, but its speed is fast. Microprogram controller is convenient in design, simple in structure, easy to modify or expand, modify the function of a machine instruction, only need to reprogram the corresponding microprogram;
To add a machine instruction, one simply adds a microprogram to the control memory, but it does so by executing a microprogram. The specific comparison is as follows: The combined logic controller, also known as the hard-wired controller, is composed of logic circuits and completely relies on hardware to achieve the function of instructions.
controller (controller) refers to the 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 order. 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 entire computer system.
Second, the working principle of the motor controller The motor drives the car forward, and the motor controller drives the motor to work; The motor controller consists of two parts: inverter and controller. The inverter receives the DC electric energy delivered by the battery, and converts the inverter into three-phase AC power to provide power for the automobile motor; The controller accepts the motor speed and other signals to feed back to the instrument. When braking or acceleration occurs, the controller controls the frequency rise and fall of the inverter, so as to achieve the purpose of acceleration or deceleration
