Remapping computer circuitry to cut bottlenecks: New generation computers will help cut down energy use, writes John Markoff

Abstract:
Hewlett-Packard researchers have proposed a fundamental rethinking of the modern computer for the coming era of nanoelectronics — a marriage of memory and computing power that could drastically limit the energy used by computers.

Today the microprocessor is in the centre of the computing universe, and information is moved, at heavy energy cost, first to be used in computation and then stored. The new approach would be to marry processing to memory to cut down transportation of data and reduce energy use.

The semiconductor industry has long warned about a set of impending bottlenecks described as "the wall," a point in time where more than five decades of progress in continuously shrinking the size of transistors used in computation will end. If progress stops it will not only slow the rate of consumer electronics innovation, but also end the exponential increase in the speed of the world's most powerful supercomputers — 1,000 times faster each decade.
