RISC-V’s Expanding Footprint
By Ed Sperling - 27 Aug, 2020 - Comments: 0

Zdenek Prikryl, CTO of Codasip, sat down with Semiconductor Engineering to talk about the RISC-V market, where this open instruction set architecture (ISA) is gaining ground, and what are the biggest challenges in working with this technology. SE: Where do you see the value in RISC-V? Is it for off-the-shelf processors or more customized components? Prikryl: A few years ago, RISC-V was us... » read more

Wireless Power Market Heats Up
By Bryon Moyer - 26 Aug, 2020 - Comments: 2

The wireless power market is in flux as established technologies meet newer approaches. Old standards battles have simmered somewhat, but competing messages remain. What the public ends up using will depend heavily on public charging infrastructure, but the stakes are significant. The market for battery chargers is forecast to reach $25B by 2022. Most of those chargers plug into the wall, bu... » read more

What Happened To Execute-in-Place?
By Bryon Moyer - 25 Aug, 2020 - Comments: 0

Executing code directly from non-volatile memory, where it is stored, greatly simplifies compute architectures — especially for simple embedded devices like microcontrollers (MCUs). However, the divergence of memory and logic processes has made that nearly impossible today. The term “execute-in-place,” or ”XIP,” originated with the embedded NOR memory in MCUs that made XIP viable. ... » read more

Power Amp Wars Begin For 5G
By Mark LaPedus - 24 Aug, 2020 - Comments: 2

Demand is increasing for power amplifier chips and other RF devices for 5G base stations, setting the stage for a showdown among different companies and technologies. The power amplifier device is a key component that boosts the RF power signals in base stations. It's based on two competitive technologies, silicon-based LDMOS or RF gallium nitride (GaN). GaN, a III-V technology, outperforms ... » read more

Recovery In Flat-Panel Display Biz
By Mark LaPedus - 20 Aug, 2020 - Comments: 0

The flat-panel display market is starting to recover after a period of oversupply and lackluster growth, fueled by new technologies as well as more people working from home. The flat-panel display market is complex. Several different technologies are at play, such as liquid-crystal displays (LCDs) for TV screens and other products, as well as organic light-emitting diodes (OLEDs) for smartph... » read more

Zeroing In On Biological Computing
By Katherine Derbyshire - 20 Aug, 2020 - Comments: 0

Artificial spiking neural networks need to replicate both excitatory and inhibitory biological neurons in order to emulate the neural activation patterns seen in biological brains. Doing this with CMOS-based designs is challenging because of the large circuit footprint required. However, researchers at HP Labs observed that one biologically plausible model, the Hodgkins-Huxley model, is math... » read more

Finding Defects With E-Beam Inspection
By Mark LaPedus - 20 Aug, 2020 - Comments: 0

Several companies are developing or shipping next-generation e-beam inspection systems in an effort to reduce defects in advanced logic and memory chips. Vendors are taking two approaches with these new e-beam inspection systems. One is a more traditional approach, which uses a single-beam e-beam system. Others, meanwhile, are developing newer multi-beam technology. Both approaches have thei... » read more

Monitoring Chips After Manufacturing
By Brian Bailey - 19 Aug, 2020 - Comments: 2

New regulations and variability of advanced process nodes are forcing chip designers to insert additional capabilities in silicon to help with comprehension, debug, analytics, safety, security, and design optimization. The impact of this will be far-reaching as the industry discusses what capabilities can be shared between these divergent tasks, the amount of silicon area to dedicate to it, ... » read more

The Challenge Of Keeping AI Systems Current
By Ed Sperling And Susan Rambo - 19 Aug, 2020 - Comments: 0

Semiconductor Engineering sat down to discuss AI and its move to the edge with Steven Woo, vice president of enterprise solutions technology and distinguished inventor at Rambus; Kris Ardis, executive director at Maxim Integrated; Steve Roddy, vice president of Arm's Products Learning Group; and Vinay Mehta, inference technical marketing manager at Flex Logix. What follows are excerpts of that ... » read more

Huawei: 5G Is About Capacity, Not Speed
By Ed Sperling - 18 Aug, 2020 - Comments: 3

Paul Scanlan, CTO of the Huawei Carrier Business Group in Huawei Technologies, sat down with Semiconductor Engineering to talk about 5G, which use cases are attractive and why, and how that compares with previous wireless technologies. SE: Where are you seeing 5G, and how do you see this rolling out both for sub-6GHz and millimeter wave? Scanlan: 5G is a platform for transformation. The f... » read more
