- COMP12111 - Fundamentals of Computer Engineering (Compulsory)
Additional RequirementsStudents who are not from the School of Computer Science must have permission from both Computer Science and their home School to enrol.
The module aims to give a view of the role of a digital hardware designer, taking an idea and implementing it as a silicon chip. A processor is a representative example of logic used in today's chips, also giving further insight into how computers actually work.
Having completed the module you should have developed the confidence to be able to take a concept and realise it in hardware. You should also appreciate the test and verification processes involved so that your chips work efficiently and reliably ... first time, every time!
This course unit aims to reinforce and extend digital hardware development skills which are introduced in the first year. It employs industry-standard tools and languages which are used worldwide for silicon development. The UK has perhaps the strongest expertise in Europe in these areas and skills are in high demand from employers such as ARM and Imagination Technologies who provide much of the digital design for devices such as smartphones and tablet computers.

COMP22111 reading list can be found on the School of Computer Science website for current students.
Direct feedback comes from laboratory work, both from working with the tools themselves and from the staff. Development results can (and should) be observed throughout using simulation and test. Final results are observable with a hardware realisation.
Less formal feedback is available at all times, especially during lectures and laboratory sessions.
