Advanced Control and Decode Unit Architecture for PC and MAR in Computer Systems
This document describes an advanced control and decode unit architecture utilized in computer systems, focusing on the roles of the Program Counter (PC), Memory Address Register (MAR), Instruction Register (IR), and Memory Data Register (MDR). It explains the process of data fetching, instruction decoding, and execution in a structured manner, detailing component interactions and control signals. Designed by Dr. Esam Al_Qaralleh, this architecture demonstrates the functionality of the system using constants and registers, elucidating how data is processed through multiple stages.
