Chip Errors Boost Computer Power

Posted May 25, 2010 7:51 AM

From BBC News | Technology | World Edition:

Silicon chips that are allowed to make mistakes could help ensure computers continue to get more powerful, say US researchers. As components shrink, chip makers struggle to get more performance out of them while meeting power needs. Research suggests relaxing the rules governing how they work and when they work correctly could mean they use less power but get a performance boost.

acceptable errors?.......

Now I understand that high performance jet aircraft is inheritly an unstable aircraft to acheive this high performace, and I understand that,,,,,,,and this unstable aircraft is controlled by...........computers.

I do not think its wise to lower the reference point such as a computer. There are enough errors just doing it correctly.

Yes, what is wrong here is the title of the post, maybe it was named like that on purpose, to make it sound impressive, I don't see the ethics behind this "technique".

But as you read, you realize that it's actually tollerance to those errors what free up chip resources.

people believe that computers are an absolute 1 or 0.......in essence it is. it just that how close to float decimal point you want to acheive.......

The first thing that came to mind is back in the late 80's the 386-16 math co-processor that had I believe was called the B-1 Step chip. It had some problems with additions that were incorrect., definitely a flaw, and not due to lack of accuracy.
