The control unit performs a sequence of instructions that typically includes fetching an instruction from memory, decoding it to determine the operation to be performed, and then executing the instruction by coordinating the necessary components of the CPU and other hardware. After execution, it may also involve storing the result back in memory or registers. This cycle is repeated to process subsequent instructions, facilitating the overall operation of the computer.
control unit
It is a system of coded numbers that when read by the CPU control unit are interpreted as commands for the various operations it can perform. Each different type of CPU has a differently coded instruction set.
A CPU is made up of the control unit (CU), instruction decoding unit and an arithmetic logic unit (ALU).

No, Control unit does By Bilco
every computer has a central processing unit or CPU in it to perform a specific task. a CPU contains: datat processing unit and control unit. the Data Processing Unit consists of Airthmatic logical unit and some registers and the control unit consist of some hardware and software to generate a control signal . whenever we want to perform some specific task we give computer an instruction or set of instructions called program. the definition of these instructions is stored in the memory of computer. these instruction are processed in a cyecel containing mainly three steps: 1.instruction fetch(taking instruction from memory) 2.instruction decode(understanding the meaning of an instruction) 3.instruction execution(performing the task0 each of above given step contains one or more steps further and these steps are called "microoperationS". on execution of instruction the specified task is done..
The control unit is one of the most important parts of a microprocessor for the reason that it is in charge of the entire process, that is the machine cycle. The CPU deals with each instruction it is given in a series of steps. Each step is repeated for each instruction. This series of steps is called the machine cycle. It involves:fetching an instruction from memory;decoding the instruction;transferring the data;executing the instruction.The control unit makes sure that all of those actions are carried out. It also manages all the other components on the CPU.
Different parts of instruction execution happen in different places:Control Unit - fetches, decodes, and distributes decoded instructions to other units.Arithmetic Logic Unit - performs arithmetic and logic instructions on command from Control Unit.Input/Output Unit(s) - performs input/output instructions on command from Control Unit.Memory Unit - stores instructions and data, transfers them to/from other units on command from Control Unit.
When an instruction is read from memory, it is called "fetching." This process is part of the instruction cycle, where the Central Processing Unit (CPU) retrieves an instruction from memory to execute. Fetching is the initial step, followed by decoding and executing the instruction. This sequence is essential for the proper functioning of a computer's processing capabilities.
the units of the CPU are :- ALU (arithmetic and logical unit) CU(control unit) the ALU handles the arthmetic operations being done by the application and the CU is responsible for handling the instruction passed by the micro processor.
The control unit in a basic system is responsible for interpreting instructions and managing the flow of data within the system. It typically consists of registers, decoders, and control logic circuits. The control unit fetches instructions from memory, decodes them to determine the operation to be performed, and then generates control signals to execute the operation. It coordinates the activities of the CPU components, such as the ALU and registers, to ensure that instructions are executed in the correct sequence. The design of a control unit involves careful consideration of instruction set architecture, timing requirements, and the necessary control signals to facilitate efficient and accurate execution of instructions.
The letters CPU stand for Central Processing Unit. A CPU is made up of the control unit, instruction decoding unit and an arithmeticlogic unit.
