Hello Everyone. Hoping everyone is safe and sound at their places. We are exploring some full forms and technical concepts in our previous discussions. Today’s discussion will include the Full Form Of CU In Computer.
Let’s get started with the basics of computers and then we will move to the full form of CU in Computer. Then we will discuss about the concept Of CU and the use of CU on the computer.
Revision On Computer
Through integrated hardware and software components, a computer is made to run applications and offer a range of solutions. Hardware refers to the physical parts of a computer, such as wires, transistors, circuits, and hard drives. Software, on the other hand, refers to data and programs. Full Form Of CU In Computer.

A device that can store and process information is a computer. The majority of computers employ a binary system, which performs operations including data storage, algorithm calculation, and information presentation by using the two variables, 0 and 1. It can aid in your understanding of various software and operating systems.
Full Form Of CU In Computer
The Full Form Of CU is Control Unit.
An element of a computer’s central processing unit (CPU) that controls how the processor operates is called the control unit (CU). To convert coded instructions into timing and control signals that regulate the functioning of the other units, a binary decoder is frequently utilized in a CU.
The following are the characteristics of a central processing unit (CPU). The computer’s brain is often referred to as the CPU. The CPU performs all types of data processing processes. It saves data, commands, and consequences from intermediate steps (program). It controls the operation of every part of the computer. The CPU itself is made up of the following three parts: Memory or Storage Unit, Control Unit, and ALU (Arithmetic Logic Unit). Let us move to more details regarding Control Unit.
Details On Control Unit
The computer’s monitoring unit, often known as the CU, is an essential component since it keeps track of all computer activity and enables the nation to carry out all computer-related tasks correctly.

The control unit directs the computer program to carry out the task we require of it and makes sure it is carried out. A computer’s CPU contains hardware called a control unit, or CU, which controls operations. It specifies how the computer’s logic unit, memory, and input and output devices should react to program instructions. Control unit-using devices include CPUs and GPUs.
Methods Of Designing CU
There are two methods to design a Control unit in computers. These are as follows:
Hardwired Program Control
Due to its high price, this type of control device is challenging to design. But because the CAD tool for computer design is so automated, all processors must be hardwired. It is a control mechanism that uses a finite state machine to create control signals (FSM).
- Design considerations for the hardwired control unit.
- Reduce the number of pieces of hardware you use.
- Operational speed: If a single IC can perform the same function as a group of ICs, do so. The quantity of hardware and the rate of operation are inversely correlated.
- Cost
Microprogram Control
Microprograms are used to set them apart from regular computer programs, as the name suggests. A complex instruction can be implemented in a control unit using microprogramming, which is not achievable with hardwired controls. Using a memory known as control storage creates a control mechanism (CS). The microinstruction address-generating unit transmits data to the address register, where it is decoded and transferred to the control store.

A Microprogrammed control unit with a single-level control store passes instructions from the main memory to the instruction register. After being decoded into a comprehensible form, the data is then put in the micro-instruction register’s operations section and is then received as a control signal.
Function Of CU In Computer
The control unit instructs a computer system’s test on how to execute a program’s instructions. The ALU and memory, which momentarily store data instructions and processed information, are connected via electronic signals that are directed by it. Additionally, it controls the flow of these control signals between the CPU and input/output devices. This unit is in charge of managing all the crucial computer system resources. Additionally, it makes data transfer between various hardware and the CPU possible.
Advantages Of Control Unit
Hardwired Program Control Unit :
- The amount of delay that can occur in the creation of control signals depends on the number of gates.
- To create a quick mode of operation, it can be optimized.
- It is quicker than a control unit with microprogramming.
Microprogram Controlled CU:
- The execution instruction can be easily controlled by the microprogram control unit.
- It is easily modifiable due to how simple it is to update the code.
- It can also handle complicated instructions with ease.
- A microprogram control unit’s implementation is less expensive.
This is all for today’s discussion. We will discuss more amazing stuff in the next discussions. Stay tuned.
