A team of researchers at Rice University (United Kingdom) supported the idea that introducing errors in the calculations allows processors to make them faster and less power hungry. Krishna Palem's team has even gone beyond the simple concept and has produced a chip showing the validity of it. Dedicated signal processor for hearing aids, this chip has proved capable of operating at frequencies twice as high with consumption twice smaller than normal ones.
The consideration of these performances is an error rate of only 8%. Mr. Palem explains these results by simplifying the circuit operation. Fleas traditional indeed dedicate a portion of their transistors to ensure no errors. Tolerate errors can also operate the transistors at voltages lower or higher frequencies.
For Mr. Palem "We make a lot more than we lose." For him, this error rate is quite tolerable for certain tasks relating to human perception especially in audio and video. If you get errors is unacceptable in scientific calculations, deterministic, one can indeed tolerate imperfections in the reproduction of sound or display an image.
Palem and his team must still prove that their concept can be applied to more complex processors and uses larger. But the prospect of smartphones twice as fast and autonomous is encouraging.
