Modern applications including graphics, multimedia, web search, and data analytics not only can benefit from acceleration, but also exhibit significant degrees of tolerance to imprecise computation. This amenability to approximation provides an opportunity to trade quality of the results for higher performance and better resource utilization. Exploiting(More)
—Most existing video encoders currently used in mobile applications are unable to gracefully degrade their output quality as the battery life nears its end. In other words, they cannot manage power consumption to efficiently utilize the available power resources. To be able to effectively adapt to changes in the encoder's software and hardware platforms,(More)
Despite the considerable improvements in the quality of HLS tools, they still require the designer's manual optimizations and tweaks to generate efficient results, which negates the HLS design productivity gains. Majority of designer interventions lead to optimizations that are often global in nature, for instance, finding patterns in functions that better(More)
Approximate computing provides an opportunity for exploiting application characteristics to improve performance of computing systems. However, such opportunity must be balanced against generality of methods and quality guarantees that the system designer can provide to the application developer. Improved parallel processing in graphics processing units(More)
— As the system complexity increases, the failure probability increases substantially. Therefore, the system requires techniques for supporting fault tolerance. Checkpointing technique is widely used to reduce the execution time of long-running programs in presence of failures and enhancing the reliability of such systems. Several methods were studied thus(More)
