Online PR News – 25-March-2011 – – An international team of computing experts from the United States, Switzerland and Singapore has created a breakthrough technique for doubling the efficiency of computer chips simply by trimming away the portions that are rarely used, reports Science Daily on 20 March'11

"I believe this is the first time someone has taken an integrated circuit and said, "Let's get rid of the part that we don't need," said principal investigator Krishna Palem, the Ken and Audrey Kennedy Professor of Computing at Rice University in Houston." What we've shown is that we can boost performance and cut energy use simultaneously if we prune the unnecessary portions of the digital application-specific integrated circuits that are typically used in hearing aids, cameras and other multi-media devices."

"Our initial tests indicate that the pruned circuits will be at least two times faster, consume about half the energy and take up about half the space of the traditional circuit," Expert says. He hopes that the system performs even better in the final tests, which are still underway.

Palem said the next hurdle for pruning will be to use the technique to create a complete prototype chip for a specific application. He hopes to start designing just such a chip for a hearing-aid this summer.
