Approximate Computation etc.

A lot of real-world applications don't need high accuracy computation - because they are meant for human consumption, and the human brain is an excellent pattern-interpolating/extrapolating machine. Researchers at Purdue have realized that doing this on hardware allows certain parts of the chip to run at lower voltage, thus prolonging battery life.

There is an alternate view that this can be done by software rather than hardware. (e.g. using explicit methods of integration of rate equations rather than more accurate and stable implicit schemes, etc.)

Looks like our minds won't know the difference when our devices perform a little bit of cheating. And we can use this to vastly speed up our processors / improve battery life.
