WebApr 4, 2024 · Control Unit: The Control Unit is the part of the CPU that operates all processor control signals. It controls the input and output devices and also controls the movement of instructions and data within the system. Input/Output System: Input devices are used to read data into main memory with the help of CPU input instruction. WebEU (Execution Unit) Execution unit gives instructions to BIU stating from where to fetch the data and then decode and execute those instructions. Its function is to control operations on data using the instruction decoder & ALU. EU has no direct connection with system buses as shown in the above figure, it performs operations over data through BIU.
