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.).
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
The control unit (CU) is a component of the CPU that directs the operation of the processor. It tells the computer's memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor. It directs the operation of the other units by providing timing and control signals.
The control unit (CU) decodes the instruction in the current instruction register (CIR). Then, the CU sends signals to other components within the CPU, such as the arithmetic logic unit (ALU), or back to memory to fetch operands, or to the floating-point unit (FPU).
Control unit may refer to: Control unit, a component of a computer's central processing unit; Control unit, a special area of a prison that is used to keep prisoners in solitary confinement (also called a "segregation unit") Another name for a Controller; Multipoint control unit, a device commonly used to bridge videoconferencing connections
In computing, the instruction register (IR) or current instruction register (CIR) is the part of a CPU's control unit that holds the instruction currently being executed or decoded. [1] In simple processors, each instruction to be executed is loaded into the instruction register, which holds it while it is decoded, prepared and ultimately ...

A control store is the part of a CPU's control unit that stores the CPU's microprogram.It is usually accessed by a microsequencer.A control store implementation whose contents are unalterable is known as a Read Only Memory (ROM) or Read Only Storage (ROS); one whose contents are alterable is known as a Writable Control Store (WCS).
