Maximising Microprocessor Reliability Through Game Theory and Heuristics

Embedded Systems are becoming ever more pervasive in our society, with most routine daily tasks now involving their use in some form and the market pre-dicted to be worth USD 220 billion, a rise of 300%, by 2018. Consumers expect more functionality with each design iteration, but for no detriment in perceived performance. These devices can range from simple low-cost chips to expen-sive and complex systems and are a major cost driver in the equipment design phase. For more than 35 years, designers have kept pace with Moore’s Law, but as device size approaches the atomic limit, layouts are becoming so complicated that current scheduling techniques are also reaching their limit, meaning that more resource must be reserved to manage and deliver reliable operation. With the advent of many-core systems and further sources of unpredictability such as changeable power supplies and energy harvesting, this reservation of capability may become so large that systems will not be operating at their peak efficiency. These complex systems can be controlled through many techniques, wit
