COMPUTING RESEARCH HIGHLIGHT OF THE WEEK [February 11 - 18, 2011]
Zero-Cost Self-Repair of Microprocessors
Professor Sorin and his team at Duke University have developed a hardware-free scheme, called Detouring, for tolerating permanent faults in microprocessors. Most prior self-repair schemes use significant amounts of redundant hardware, and a fault in one unit can be tolerated by using another unit of the same kind. The problem with these approaches is the cost and power consumption of the redundant hardware. The NSF-funded Detouring research, instead of adding redundant hardware, translates software such that it does not use any of the faulty hardware. Detouring thus has zero hardware cost, and it incurs no performance penalties in the fault-free case.

Computing Research Highlight of the Week is a service of the Computing Community Consortium and the Computing Research Association designed to highlight some of the exciting and important recent research results in the computing fields. Each week a new highlight is chosen by CRA and CCC staff and volunteers from submissions from the computing community. Want your research featured? Submit it!.
