System Bits: Sept. 27


Memory management scheme accommodates commercial chips In an improvement to a memory management scheme presented last year in which MIT Computer Science and Artificial Intelligence Laboratory researchers unveiled what they said was a fundamentally new way of managing memory on computer chips — one that would use circuit space much more efficiently as chips continue to comprise more and more... » read more

Making electrons act like liquid While electrical resistance is a simple concept in that rather like friction slowing down an object rolling on a surface, resistance slows the flow of electrons through a conductive material, and now, MIT professor of physics Leonid Levitov and Gregory Falkovich, a professor at Israel’s Weizmann Institute of Science have found that electrons can sometimes tur... » read more

World neutrino record The U.S. Department of Energy’s Fermi National Accelerator Laboratory has achieved a world record for high-energy neutrino experiments. In one neutrino experiment, researchers sustained a 521-kilowatt beam generated by the organization’s so-called Main Injector particle accelerator. The previous record was a 400-plus-kilowatt beam, which was accomplished at CERN. ... » read more

Power/Performance Bits: March 10


Simulated memories Resistance-switching cells hold promise as a faster, higher capacity, lower power replacement for current non-volatile memory. Yet "the mechanisms that govern their remarkable properties have been poorly understood, limiting our ability to assess the ultimate performance and potential for commercialization," said Alejandro Strachan, professor of materials engineering at Pu... » read more

Sensing objects without looking at them In a technique known as “interaction-free measurement,” Yale engineers have created a chip-scale device that senses the presence of an object without interacting with it by using the wave-particle duality of single photons. This work could help propel the field of quantum information processing. The researchers explained that the device uses silic... » read more

The Week In Review: Design


Tools Cadence unveiled two new tools. The first is a rapid prototyping platform that the company claims will shorten bring-up time by 70%, with 4X improvements in capacity, with IEEE 1801 support for low-power verification through its emulation platform. The second is a single and multi-corner custom/analog extraction tool, which it claims will improve performance by 5X. The tool has been cert... » read more
