Computer Hardware 'Guardians' Protect Users From Undiscovered Bugs

ScienceDaily (2008-10-01) -- As computer processor chips grow faster and more complex, they are likely to make it to market with more design bugs. But that may be OK, according to researchers who have devised a system that lets chips work around all functional bugs, even those that haven't been detected. [more]

This is pretty cool. Here is more from the article:

The approach keeps track of all the configurations the firm did test, and loads that information onto a minuscule monitor that would be added to each processor.

The monitor, called a semantic guardian, keeps the chip operating within its virtual fence. It works by switching the processor into a slower, bare-bones, safe mode when the chip encounters a configuration that has not been validated. In this way, the monitor would treat all untested configurations as potential threats.
