IBM researchers have unveiled a new liquid power and cooling solution for computers that it has dubbed “electronic blood.” Continue reading
It’s been a big year for nanophotonics, the technology that makes it possible to build chips that use pulses of light to communicate. A year ago we wrote about progress at MIT in developing photonic chips that use light beams to perform computational tasks. Now IBM has announced it has developed a scalable silicon nanophotonics chip on the path to enabling 100 Gpbs networks. Continue reading
IBM scientists at the T.J. Watson Research Center have come up with a way to use carbon nanotubes to build faster, smaller microprocessors with more transistors.
The research, which appeared in a recent edition of Nature Nanotechnology, involves creating an array of carbon nanotubes on the surface of a silicon wafer to build chips with more than 10,000 transistors. IBM has done so at a scale where silicon simply doesn’t work, and by packing so many transistors on to such a tiny area could boost CPU performance significantly. Continue reading
With so much information traveling hither and yon on the Internet (especially if you’re doing simulation or renderings via the cloud), improvements in speed are something of a Holy Grail (yeah, I went there) for scientists. Chips that use light beams instead of electrons seem to be the way forward. We covered MIT’s foray into photonic chips earlier on EE and now IBM Labs has released its first prototype.
The Holey Optochip is a parallel optical transceiver that has managed to break 1 terabit (that’d be 1 trillion bits) per second. For some perspective, that would allow users to download 500 HD movies in a second, or the entirety of the Library of Congress in about an hour.
