Introduction
• CPU can be stated as the part of the
computer which executes the given program
instruction.
• It mainly comprises of three major
components that is ALU and register.
• The control unit aims to direct movement of
electrical signal in between the memory.
• Each of the set of instruction comprises of
microcode

Different processor registers in the fetch execute
cycle
There are large number of circuits being used
at the cycle phase that are
• Program counter
• Memory Address register
• Memory Buffer Register
• Current instruction register
• Accumulator
• Status register
