Dynamically Exploiting Narrow Width Operands to Improve Processor Power and Performance
In general-purpose microprocessors, recent trends have pushed towards 64-bit word widths, primarily to accommodate the large addressing needs of some programs. Many integer proble...

Evaluating Techniques for Exploiting Instruction Slack
In many workloads, 25% to 50% of instructions have slack allowing them to be delayed without impacting performance. To exploit this slack, processors may implement more power-efï¬...

Exploiting program execution phases to trade power and performance for media workload
Abstract- Processing streaming media comprisesseveral program phases (often distinct) that are periodic and independent of application data. In this paper we characterize execution...

Relationship between power loss and network topology in power systems
This paper is concerned with studying how the minimum power loss in a power system is related to its network topology. The existing algorithms in the literature all exploit nonline...

A standby-sparing technique with low energy-overhead for fault-tolerant hard real-time systems
Time redundancy (rollback-recovery) and hardware redundancy are commonly used in real-time systems to achieve fault tolerance. From an energy consumption point of view, time redun...
