COM165 Computer Systems Architecture

Summary This module introduces the important elements of computer architecture including digital logic, computer arithmetic and instruction set architecture. The approach in the module is to show how the basic elements of a computer are constructed and combined to give sophisticated architectures that support accelerated performance via cache memory and pipelining.

Resources
Aims The aim of this module is to give a fundamental knowledge and understanding of the basic computer structures that underlie computer architectures.
Objectives By the end of this module students should:
  • know how to design functional units using combinatorial and sequential logic;
  • understand the computer representation of integer and floating-point numbers;
  • understand and be able to describe the components of a computer system, and the interfaces between them;
  • understand the structure of a typical computer instruction set, and be able to explain the function of instructions using RTL notation;
  • understand and be able to write simple programs in assembly language;
  • understand how system performance can be accelerated by use of pipelining and cache memory.
