Overview

The module is a strong practical reinforcement of the software/hardware interface. It provides experience in hardware/software codesign as well as dealing with interfacing techniques, from 'bit fiddling' to interrupt routines. There is also an underpinning of operating systems and their implications in machine architecture. The module uses custom designed hardware and software tools developed locally for this specific purpose.

Pre/co-requisites

Unit title Unit code Requirement type Description
Fundamentals of Computer Architecture COMP15111 Pre-Requisite Compulsory
Students who are not from the School of Computer Science must have permission from both Computer Science and their home School to enrol.

Aims

This course aims to familiarise students with the use of microprocessors/microcontrollers for simple control and interfacing applications. The course aims to develop the understanding of the programming and operation of the ARM processor introduced in COMP15111 to include modular program construction, separation of user and operating system tasks and interfacing techniques at the hardware and software levels.

This course builds upon the understanding of processor operation and assembler programming introduced in COMP15111 and upon the logic design in introduced in COMP12111 to show how hardware and software interact in the solution of interfacing problems.

This module currently runs as a first year CSE course or a second year CS course. There is some variation towards the end of the module to accommodate different backgrounds.

Learning outcomes

  • interface, from the software side input and output devices with an embedded controller

  • customise simple digital I/O hardware

  • properly understand the von Neumann memory architecture (I can't think of a circumlocution which expresses this any better even if it does use a naughty word!)

  • write reasonably sizeable assembly language routines with all the familiarity with processor architecture that entails

  • write I/O software for parallel interfaces, including time-division multiplexing and timers

  • write interrupt-driven code

  • structure, lay-out and document code to a maintainable standard
