A Holistic Approach To Energy-Efficient System-On-Chip (SoC) Design
By Synopsys - 10 May, 2022 - Comments: 0

It takes a great deal of energy to power the modern world, and demand grows every day. This is especially true for electronics, where ever increasing automation and more intelligent devices incessantly demand more power. Many applications that use chips face a variety of pressures for reduced power consumption and better energy efficiency. In response, the semiconductor and electronic design au... » read more

Research Bits: May 9

Optical oscilloscope Researchers from the University of Central Florida developed an optical oscilloscope to measure the electric field of light. The high speed at which light oscillates has made reading its electric field challenging, with current instruments able to resolve an average signal associated with a pulse of light rather than individual peaks and valleys within the pulse. “... » read more

Rambus To Buy Hardent
By Ed Sperling - 05 May, 2022 - Comments: 0

Rambus inked a deal to buy Hardent, an engineering services company, in order to accelerate Rambus' push into the CXL arena. Compute Express Link (CXL), developed primarily by Intel before being turned into an open industry standard, allows memory to be disaggregated within a data center and shared across multiple servers. This, in turn, lets data centers control how critical resources are a... » read more

Startup Funding: April 2022
By Jesse Allen - 04 May, 2022 - Comments: 0

Silicon photonics holds the potential to vastly increase bandwidth in chips and systems while reducing power use — and investors are taking note. In April, one of the largest funding rounds went to a startup developing chip-to-chip optical I/O. But that wasn't all. Photonics funding showed up in AI with a photonic Tensor core, in room-temperature quantum computing, and, of course, in lidar an... » read more

Fingerprinting quantum noise Scientists from the University of Chicago and Purdue University propose a different method of understanding the effect of noise in quantum computers. Instead of trying to measure it directly, they created a 'fingerprint' of how the noise impacts a program run on the computer. “We wondered if there was a way to work with the noise, instead of against it,” sai... » read more

Photonic quantum computers Researchers from Stanford University propose a simpler design method for photonic quantum computers. The proposed design uses a laser to manipulate a single atom that, in turn, can modify the state of the photons via a phenomenon called “quantum teleportation.” The atom can be reset and reused for many quantum gates, eliminating the need to build multiple distinc... » read more

More Options, Less Dark Silicon
By Ed Sperling - 20 Apr, 2022 - Comments: 0

Chipmakers are beginning to re-examine how much dark silicon should be used in a heterogenous system, where it works best, and what alternatives are available — a direct result of a slowdown in Moore's Law scaling and the increasing disaggregation of SoCs. The concept of dark silicon has been around for a couple decades, but it really began taking off with the introduction of the Internet ... » read more

Processor power prediction Researchers from Duke University, Arm Research, and Texas A&M University developed an AI method for predicting the power consumption of a processor, returning results more than a trillion times per second while consuming very little power itself. “This is an intensively studied problem that has traditionally relied on extra circuitry to address,” said Zhiy... » read more

Energy Harvesting Starting To Gain Traction
By John Koon - 18 Apr, 2022 - Comments: 4

Tens of billions of IoT devices are powered by batteries today. Depending on the compute intensity and the battery chemistry, these devices can run steadily for short periods of time, or they can run occasionally for decades. But in some cases, they also can either harvest energy themselves, or tap into externally harvested energy, allowing them to work almost indefinitely. Energy harvesting... » read more
