The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).

Dec 28, 2024 · What is a Control Unit? The Control Unit is the part of the computer’s central processing unit (CPU), which directs the operation of the processor. It was included as part of the Von Neumann Architecture by John von Neumann.

控制单元，英文Control Unit（CU），是CPU部件之一，有时也安装于CPU外部。 其基本功能是从内存取指令、分析指令和执行指令。 控制单元是实现一种或多种控制规律的 控制仪表 或 控制部件 。

控制單元（Control Unit），有時為CPU一部分，有時安裝於CPU外部，負責指揮CPU工作。 通過該裝置的運行來控制其他裝置的活動，也被視作 有限狀態自動機 的一種。

The control unit controls the movement of data, memory read and write operations between the processor and the main memory RAM. The control unit generates the steady stream of clock pulses that regulates speed of the instruction cycle. The instruction cycle is performed by the CPU to execute the program instructions.

Jun 29, 2020 · A Control Unit or CU is circuitry that directs operations within a computer's processor. It lets the computer's logic unit, memory, and both input and output devices know how to respond to instructions received from a program.

Dec 15, 2023 · 控制单元（Control Unit）是中央处理器（CPU）的一个重要组成部分，它主要负责控制指令的执行过程，包括指令的取指、分析、解码和执行等。 控制单元的工作原理是：从内存中读取指令，并根据指令的操作码（Opcode）...

Feb 11, 2025 · A control unit, or CU, is among the three components of the CPU, alongside the arithmetic and logic unit and memory unit. It regulates the processor’s or CPU’s operations. It governs the two other CPU components, the arithmetic and logic unit and memory unit, and input and output devices and tells them how to respond to instructions sent to ...

control unit, subcomponent of a central processing unit (CPU) that manages a computer’s operations. The control unit fetches instructions from the CPU’s memory, represented in bits, and translates those instructions into control signals in the form of pulses of electricity or light.

These control signals facilitate flawless execution of instructions in CPU, handling of Interrupts and internal errors by CPU, communication over the internal bus (es) in CPU, communication over the external bus (external Datapath) to memory and IO subsystem. A Control unit is part of the CPU subsystem.
