COMP25212: System Architecture (2011-2012)
The basic architecture of computer systems has been covered in first year course units which detailed both the instruction set architecture and the micro-architecture (hardware structure) of simple processors. Although these principle underlie the vast majority of modern computers, there are a wide range of both hardware and software techniques which are employed to increase the performance, reliability and flexibility of systems.
The aims of this course are to introduce the most important system architecture approaches. To give a wider understanding of how real systems operate and, from that understanding, the ability to optimise their use.
