Powering and Cooling a Wafer Scale Die | EE Times


Has Cerebras solved the classic wafer-scale challenges?

Amid a flurry of announcements from SC ’19, there was one in particular that caught my eye.

You may remember EETimes’ coverage of the Cerebras wafer-scale AI accelerator from back in the summer. The company’s wafer scale engine (WSE) is made up of processing tiles that fill an entire wafer – overall there are 1.2 trillion transistors, 400,000 compute cores and 18GB of on-chip memory.

In short, it’s a monster, but a monster specifically created to face the unique challenges of processing AI workloads.

Powering and cooling such a large device was also a big question mark.

Cadence Consolidates RF Design with AWR Buy | EE Times

For $160 million, Cadence will get board- and system-level RF design capabilities to complement its circuit-level RF expertise.

Cadence Design Systems is purchasing National Instruments subsidiary AWR Corp. for $160 million. In conjunction with the acquisition, Cadence and NI, which have been working together for some time, have also entered a strategic alliance to work in tandem to serve mutual customers in the communications sector.

ChangXin Emerging as China’s First & Only DRAM Maker | EE Times


ChangXin Memory (CXMT) has claimed the distinction of being — officially — “China’s only DRAM producer.”

China is boastful of its plan to produce homegrown memory devices, but aside from the NAND flash memory in the works at Yangtze Memory Technologies Co., Ltd. (YMTC) and NOR flash designed by GigaDevice, China has had more ambition than results.

Creating DRAM would be a big step in validating China’s semiconductor ambitions, but industry opinion has been split on whether China can deliver DRAM at all. Even if it does, observers ask how soon China can start shipping commercial DRAMs in meaningful volume.

30 Reasons Why Licensing Huawei 5G Could be a Bad Idea | EE Times


Markets. The primary markets for this proposal are those that have banned Huawei, namely the USA and some allied nations. In every market, the new company could expect fierce competition from others.

Scale. Where does this new venture compete, and how does it gain sufficient economy of scale? The banishment markets are not enough, not even for Nokia and Ericsson.

Supply chain. Be sure that Huawei (and China Inc.) are working furiously to rid themselves of American choke points – it is an existential issue. What happens to the new entity when it needs to source the Chinese components and then sell into the banishment markets?

Qualcomm Battles 5G ‘Misconceptions’ | EE Times


Qualcomm stormed the beaches of Maui this week to host Qualcomm Tech Summit, an annual boondoggle for media and analysts from everywhere, with a single objective: to debunk “5G misconceptions” allegedly entrenched in the market and trumpeted by the press.

These misconceptions, according to Qualcomm, range from “mmWave is not really happening yet” and “5G rollout will take a long time,” to “where are all the 5G apps?” The communication chip giant insisted that all this can be easily debunked.

Ultra-low Power Bionic Chip Treats Alzheimer’s | EE Times


The first artificial digital neuron has been created in the laboratory, with the aim of restoring lost brain functions. Scientists plan to use these chips to treat neurodegenerative diseases.

Alzheimer’s is a neurodegenerative disease that involves a progressive death of neurons with cognitive, behavioral, and motor consequences; it is a bit like taking away the soul of the person affected, devastating not only for patients but also their families. Alzheimer’s disease remains difficult to treat, but researchers are exploring new nanotechnology solutions that might help improve the quality of life of those afflicted.

An international research team led by scientists from the British University of Bath in the U.K. has created the first artificial neurons in the laboratory, miniature devices designed to repair nerve circuits and restore lost functions. Scientists plan to use such bionic chips to treat both heart-related and neurodegenerative diseases.

Global IC Sales Continue Their Dive | EE Times


The memory segment, a drag on the market in 2019, appears to be reviving, however, and promises to get stronger in 2020.

Global semiconductor sales continued to decline in the third quarter of 2019, despite growth signs in the memory market. Meanwhile, Intel retains top slot in global rankings, while Sony Semiconductor Solutions is a shining star as it entered the top 10.

In aggregate, semiconductor revenue for the first three quarters of 2019 fell by $52 billion, representing a 14.2 percent drop compared to the first three quarters of 2018.

Preparing the next generation of GPS | Intelligent Aerospace


CBS takes a look at the United States Air Force’s military and civilian global positioning system (GPS) program, including how the Air Force protects against GPS jammers, and touches on the capabilities of Lockheed Martin’s GPS III system that will be online soon. Two of the GPS III satellites are currently in orbit.

GPS III has three times better accuracy and up to eight times improved anti-jamming capabilities. Spacecraft life will extend to 15 years, 25 percent longer than any of the GPS satellites on-orbit today.

What’s more fancy than a Porsche? A flying Porsche. Luxury automakers race to perfect the flying car | Intelligent Aerospace


A 2018 study by Porsche Consulting forecasts that the urban air mobility market will pick up speed after 2025. The study also indicates that urban air mobility (UAM) solutions will transport passengers more quickly and efficiently than current conventional means of terrestrial transport, at a lower cost and with greater flexibility.

Porsche’s Stuttgart, Germany neighbor Mercedes-Benz has also dipped its toes into the UAM world with its investment into Volocopter.
