Detailed explanation-1: -The functions of the control unit include the following. It directs the flow of data sequence between the processor and other devices. It can interpret the instructions and controls the flow of data in the processor.
Detailed explanation-2: -During the decode stage, the control unit (CU) will decode the instruction in the CIR. The CU then sends signals to other components within the CPU, such as the arithmetic logic unit (ALU) and the floating point unit (FPU).
Detailed explanation-3: -The Instruction Decoder is a CPU component that decodes and interprets the contents of the Instruction Register, i.e. its splits whole instruction into fields for the Control Unit to interpret. The Instruction decoder is often considered to be a part of the Control Unit.
Detailed explanation-4: -The CPU is now ready to carry out the fetch decode execute cycle. The Control Unit sends a signal to the RAM in order to fetch the program and data, which is then stored in one of the CPU’s register. To do so, the CPU makes use of a vital hardware path called the ‘address bus’ along which the program and data travels.
