Computer Architecture Laboratory (ACAL) received a 2006
Choice Award in the newly created category, Innovation. ACAL was named
with industrial partner ARM, Ltd. for
introducing and implementing the technology called Razor, which MPR believes
“is relevant to power consumption and the concept of future computing in
Razor is a novel design methodology that eliminates the safety margins
and uses self-checking mechanisms to ensure computational correctness in
presence of errors. Thus, it represents a radical departure from the
traditional design paradigm of "worst-case" and "always-correct" to
"typical-case" and "usually-correct". Using in situ error detection and
correction mechanisms, a "Razor"-ed pipeline is able to dynamically adjust
its supply voltage or frequency to operate at exact point of failure. Since
its inception in 2003, Razor has consistently evolved over the years.
MPR stated that they are making the award on the basis of ARM, Ltd’s
announcement that it is planning to implement the technology.
Principle architects of Razor and the ACAL/ARM collaboration are Profs.
and Trevor Mudge, the Bredt
Professor of Electrical Engineering and Computer Science. In additional,
several ACAL students and alumni have been involved in the research.
Krisztián Flautner, director of advanced research at ARM, completed his
dissertation under Mudge. Current students, such as Shidhartha Das, are
working with ARM on a prototype of the razor technology.

specifically targeting wireless and low-power computing, see a recent
