Postgraduate Course: Energy Aware Computing (Level 11) (INFR11052)
|School||School of Informatics
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Not available to visiting students
|Summary||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 and evaluate selected methods in research simulators and to critically review literature in this field.
