Undergraduate Course: Energy Aware Computing (Level 10) (INFR10031)
|School||School of Informatics
||College||College of Science and Engineering
||Availability||Available to all students
|Credit level (Normal year taken)||SCQF Level 10 (Year 4 Undergraduate)
|Home subject area||Informatics
||Other subject area||None
||Taught in Gaelic?||No
|Course description||This course aims to introduce students to basic concepts and modern techniques in designing, modelling and evaluating energy-efficient computing systems. Low energy/power consumption is the most important design issue in modern computing devices as it has a direct impact not only on the battery life of mobile electronic equipment, but also sets limits on the operating speed of high-performance computing devices. This course will examine techniques to improve energy consumption at circuit (logic gate), micro-architecture, memory hierarchy and, at a lesser degree, at OS, compiler levels. It will also introduce state of the art approaches to energy aware computing by examining selected research papers. Practical coursework will require students to implement selected methods in research simulators and evaluate their performance.

Summary of Intended Learning Outcomes
|1 - describe and discuss the factors which contribute to the consumption of power/energy in computing systems and how they affect the system performance.
2 - explain in detail mechanisms found in modern computing systems for conserving energy.
3 - discuss, assess and compare the behaviour and performance of energy-saving techniques on computing micro-architectures
4 - gain familiarity with state-of-the-art tools such as processor simulators, memory models and compilers, and use them to implement and evaluate techniques described in the technical literature.
5 - write and present clear and concise descriptions of complex systems/methods.
