Catalog Description

The Objective of this course is to expose the students to the fundamentals and the concepts of Digital & Computer Organization and Representation of Information and Basic Building Blocks, Basic Organization, Memory Organization, Input-Output Organization, Processor Organization etc. This course is designed to understand the concepts of Computer Organization for Research & Development as well as for application.

 

Course Objectives

The objective of this course is to

  1. An understanding of a machine’s instruction set architecture (ISA) including basic instruction fetch and execute cycles, instruction formats, control ow, and operand addressing modes. 

Course Outcomes

On completion of this course, the students will be able to:

CO1: Understand and Interpret the functional architecture of computing systems.

CO2.  Identify, compare and assess issues related to ISA, memory, control and I/O functions.

CO3.  Understand the general concepts in digital logic design, including logic elements, and their use in combinational and sequential logic circuit design.

CO4.  Design and analyse solutions in the area of computer architecture.
