1TGE120011R1110 Motor & Feeder Control Unit for MNS iS

The Control Unit (CU) is one of the core components of the computer, mainly responsible for the

process management of the program. It is the command and control center of the CPU, similar to

the logistics distribution department of the factory, and plays a coordinating role in the orderly work of the entire computer.

The basic function of the control unit is to fetch instructions from memory, analyze instructions and

execute instructions. It consists of three parts: instruction register (IR), instruction decoder (ID) and

operation controller (OC). The instruction register is used to store the instructions taken from memory, and

the instruction decoder decodes the instructions to determine what operations should be performed.

The operation controller sends a microoperation control signal to the corresponding

component according to the decoding result and the determined timing.

There are two main ways to implement the control unit: microprogram type and hardware type control

unit. The microprogrammed control unit reads and sends out the control signal through the microprogram,

while the hardware control unit sends out the control signal directly through the digital path. With the

development of integrated circuit scale and design technology, hardware-based control unit has become possible.

The control unit is widely used in various fields of computer, for example, the engine control unit (ECU)

is used to control the fuel injection, ignition and emission of the engine. The body control unit (BCM) is

used to control the various electrical appliances and systems of the body, such as doors, Windows, lights,

sound, etc. The anti-lock braking system control unit (ABS) is used to control the anti-lock braking

system to ensure that the vehicle can remain stable during braking. The Electric Power Steering Control

Unit (EPS) controls the electric power steering system to provide more flexible and accurate steering feedback;

The airbag control unit is used to control the operation of the airbag to ensure that it can be ejected in time in the event of a collision.

In general, the control unit is an indispensable part of the computer, and its function and effect have an

important impact on the operation of the entire computer system.
