Power/Performance Bits: Sept. 26


Long-range communication Researchers at the University of Washington developed devices that run on almost zero power can transmit data across distances of up to 2.8 kilometers. The long-range backscatter system, which uses reflected radio signals to transmit data at extremely low power, achieved reliable coverage throughout 4800-square-foot house, an office area covering 41 rooms and a one-acr... » read more

DARPA CHIPS Program Pushes For Chiplets


While the semiconductor industry plugs away at More Than Moore innovation, the U.S. government is guiding its own SoC development. A new program kicked off last year called ‘Common Heterogeneous Integration and IP Reuse Strategies’ or CHIPS to take its own approach the incredibly high cost of SoC design and manufacturing. DARPA said it recognizes that the explosive growth in mobile and t... » read more

Power/Performance Bits: May 16


Chaos-based IC Researchers at North Carolina State University and the College of Wooster developed a three transistor nonlinear, chaos-based integrated circuit combining digital and analog components, which they hope can improve computational power by enabling processing of a larger number of inputs. In chaos-based, nonlinear circuits, one circuit can perform multiple computations instead... » read more

GaN-on-GaN power semis Power semiconductors based on gallium nitride (GaN) are heating up in the market. Typically, suppliers are shipping devices using a GaN-on-silicon process. These devices are available with blocking voltages of up to 650 volts. Going beyond 650 volts is problematic, however. GaN-on-silicon processes suffer from lattice mismatches, cost and other issues. At the ... » read more

Power/Performance Bits: Sept. 13


Core-to-core communication Most research featured in the Power/Performance Bits has far-off applications, but a team from North Carolina State University and Intel developed something that could be brought into practice today: a way to accelerate core-to-core communication. Many important workloads incur significant core-to-core communication and are affected significantly by the costs, i... » read more

What’s Missing From Machine Learning


Machine learning is everywhere. It's being used to optimize complex chips, balance power and performance inside of data centers, program robots, and to keep expensive electronics updated and operating. What's less obvious, though, is there are no commercially available tools to validate, verify and debug these systems once machines evolve beyond the final specification. The expectation is th... » read more

Rolling Out Solar Power...Literally An International team of researchers have developed solar cells that can be added onto a roll of flexible plastic in liquid form, bringing the same kind of economies of production to the solar industry as rolls of paper and ink did for newspapers more than a century ago. Using a roll-to-roll processing method, the team was able to achieve a power conversi... » read more

Jumping films Riken and the University of Tokyo have developed a tiny autonomous actuator. The actuator, which is based on a special material, can automatically curl up or straighten out when exposed to ambient humidity. And in certain conditions, the film can even jump into the air by itself. A video can be seen here. Researchers placed a material called guanidinium carbonate into a hig... » read more

How To Build Systems In Package


The semiconductor industry is racing to define a series of road maps for semiconductors to succeed the one created by the ITRS, which will no longer be updated, including a brand new one focused on heterogeneous integration. The latest entry will establish technology targets for integration of heterogeneous multi-die devices and systems. It has the support of IEEE's Components, Packaging and... » read more

Power/Performance Bits: Jan. 5


A foggy consortium Scientists at Princeton University, ARM, Cisco, Dell, Intel, and Microsoft formed a global effort to develop architectures and tools to further "fog computing" and networks, which aim to harness connected devices' own computing, sensing and storage power to form edge networks that meet most of the demand of user devices that are at the periphery of a more centralized netwo... » read more
