System Bits: Aug. 16
By Ann Mutschler - 16 Aug, 2016 - Comments: 0

Record-breaking quantum logic gate Reaching the benchmark required theoretically to build a quantum computer, University of Oxford researchers have achieved a quantum logic gate with record-breaking 99.9% precision. They reminded that quantum computers, which function according to the laws of quantum physics, have the potential to dwarf the processing power of today's computers, able to pro... » read more

System Bits: Aug. 9

Using trapped ions as quantum bits MIT researchers reminded that quantum computers are largely hypothetical devices that could perform some calculations much more rapidly than conventional computers can, and instead of the bits of classical computation — which can represent 0 or 1 — quantum computers consist of quantum bits, or qubits, which can, in some sense, represent 0 and 1 simultaneo... » read more

Will Open-Source Work For Chips?
By Brian Bailey - 30 Jun, 2016 - Comments: 2

Open source is getting a second look by the semiconductor industry, driven by the high cost of design at complex nodes along with fragmentation in end markets, which increasingly means that one size or approach no longer fits all. The open source movement, as we know it today, started in the 1980s with the launch of the GNU project, which was about the time the electronic design automation (... » read more

System Bits: June 21

Faster running parallel programs, one-tenth the code MIT researchers reminded that computer chips have stopped getting faster and that for the past 10 years, performance improvements have come from the addition of cores. In theory, they said, a program on a 64-core machine would be 64 times as fast as it would be on a single-core machine but it rarely works out that way. Most computer programs... » read more

Alternative To x86, ARM Architectures?
By Jeff Dorsch - 07 Jun, 2016 - Comments: 1

Software developed by professors and graduate students from the University of California at Berkeley? That will never fly in the semiconductor industry, right? Maybe they said that about SPICE, four decades ago. The jury is still out on RISC-V (pronounced risk-five) the modular, open-source instruction set architecture created in this decade by Cal professors and students, yet the ISA is gai... » read more

Power/Performance Bits: May 24

Reducing MRAM chip area Researchers from Tohoku University developed a technology to stack magnetic tunnel junctions (MTJ) directly on the via without causing deterioration to its electric/magnetic characteristics. The team focused on reducing the memory cell area of spin-transfer torque magnetic random access memory (STT-MRAM) in order to lower manufacturing costs, making them more compe... » read more

Power/Performance Bits: April 19

Ferroelectric non-volatile memory Scientists from the Moscow Institute of Physics and Technology (MIPT), the University of Nebraska, and the University of Lausanne in Switzerland succeeded in growing ultra-thin (2.5-nanometer) ferroelectric films based on hafnium oxide that could potentially be used to develop non-volatile memory elements called ferroelectric tunnel junctions. The film was g... » read more

What Cognitive Computing Means For Chip Design
By Ann Mutschler - 30 Mar, 2016 - Comments: 1

Cognitive computing. Artificial intelligence. Machine learning. All of these are concepts aim to make human types of problems computable, whether it be a self-driving car, a health care-providing robot, or a walking and talking assistant robot for the home or office. R&D teams around the world are working to create a whole new world of machines more intelligent than humans. Designing sys... » read more

Power/Performance Bits: March 15
By Jesse Allen - 15 Mar, 2016 - Comments: 0

Magnetic computing Engineers at the University of California, Berkeley, demonstrated that magnetic chips can operate with the lowest fundamental level of energy dissipation possible under the laws of thermodynamics. "We wanted to know how small we could shrink the amount of energy needed for computing," said Jeffrey Bokor, a UC Berkeley professor of electrical engineering and computer sci... » read more

Enabling Self-Driving Cars
By Ann Mutschler - 09 Mar, 2016 - Comments: 1

To enable truly self-driving cars — the ones without a gearshift or a steering wheel — there must be a confluence of technologies, a refinement of the business models, regulatory and safety requirements, and insurance concerns. So how close is the automotive ecosystem to reaching the goal of truly autonomous driving? That depends on your vantage point. As far as where automakers are t... » read more
