Microprocessor design

Overview

The logic circuit inside a microprocessor consists of two main parts, a datapath and a control unit. The datapath is responsible for the manipulation of all data operations to be performed by the microprocessor. The control unit is a finite state machine that is responsible for controlling the sequence of operations to be performed by the datapath in order to produce the microprocessor's desire output.

Designing a microprocessor involves the systematic design of its datapath and control unit.
