Reconfigurable Chaos-Based Microchips

Researchers at North Carolina State University have developed nonlinear chaos-based integrated circuits that enable computer chips to perform multiple functions with fewer transistors. These integrated circuits can be manufactured with off-the-shelf fabrication processes, and could lead to novel computer architectures that do more with less circuitry and fewer transistors.

Supercomputer Cooling System Uses Refrigerant to Replace Water

Sandia National Laboratories researchers designed a cooling system for supercomputer centers that is expected to save four to five million gallons of water annually in New Mexico if installed at Sandia's computing center, and hundreds of millions of gallons nationally if the method is widely adopted. It is being tested at the National Renewable Energy Laboratory (NREL), which expects to save a million gallons annually. The system, built by Johnson Controls and called the Thermosyphon Cooler Hybrid System, cools like a refrigerator without the expense and energy needs of a compressor.

Computer Chips Calculate and Store in an Integrated Unit

Researchers at the University of Wisconsin-Madison created computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit, and communicate efficiently with other chips. Called “liquid silicon” — liquid for software and silicon for hardware — the technology has uses in data-intensive applications such as facial or voice recognition, natural language processing, and graph analytics.

Electron-to-Photon Communication for Quantum Computing

Princeton University researchers have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, then acts as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer.

Material Combination Enables Transistor Gate Length of 1 Nanometer

The laws of physics have set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end, 20-nanometer-gate transistors now on the market. Researchers from the Department of Energy's Lawrence Berkeley National Laboratory have created a transistor with a working 1-nanometer gate.

Key Considerations for Powertrain HIL Test

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.
