Getting started with Embedded Linux

Linux’s origins can be traced back to the commercially available Unix operating, but it wasn’t until Finnish student Linus Torvalds announced a free Linux kernel in 1991 that the open source operating system movement really started to gain traction Today, there are several popular Linux distributions that are designed for use with SBCs, an example being the Debian-based Raspbian distribution for use with the Raspberry Pi.

Huawei honours Turkish professor for 5G polar codes

The company also honoured more than 100 Huawei scientists and engineers who have worked on standards and basic research.

Professor Arikan published his seminal paper on polar codes in 2008 and defined an approach that could improve the rate and reliability of data transmission. Polar codes are the world's first channel coding scheme to bring us up against the threshold of Shannon's limit, or the maximum rate that data can be sent with zero error at a particular bandwidth.

Ultrasound sensor market set for take off

The company reports that some new applications are showing good demand for either capacitive micromachined ultrasonic transducers (CMUTs) or piezoelectric micromachined ultrasonic transducers (PMUTs).

Cambridge touchscreen developer attracts Chinese cash

Existing investors Parkwalk Advisors, Cambridge Enterprise and Amadeus Capital Partners participated in the round, and were joined by new investors China Materialia of Shanghai and Downing Ventures of London.

CTT uses a transparent piezoelectric film on display surfaces to enable multi-finger 3D touch and it is claimed that once in volume production it will be a fraction of the cost of existing approaches. The technology detects both position and the force applied.

Metamaterial startup raises funds to improve automotive radar

The latest funding brings the amount raised by Metawave to $17 million. The company, founded in 2017, is using a combination of metamaterials and artificial intelligence methods with an initial focus on smart radar platforms, for Advanced Driver Assistance Systems (ADAS) and autonomous driving. Metawave plans to also work onsmart antenna platforms for fixed wireless and the 5G cellular infrastructure to power point-to-point, point-to-multipoint, and mesh configurations for backhaul and access networks.

IDM or foundry: CanSemi builds on analog, MCU strategy

CanSemi Technology Inc. broke ground on its 300mm wafer fab on December 26, 2017 and claims to have 7 billion yuan (about US$1 billion) of investment available. It will make chips using manufacturing processes from 0.18-micron down to 0.13-micron but what remains unclear is whether CanSemi will be an integrated device manufacturer or a foundry – or will try to fulfil both functions.

Cadence, Nvidia to apply machine learning to EDA

The Machine learning-driven Automatic Generation of Electronic Systems Through Intelligent Collaboration (MAGESTIC) project is set to last four years and will include machine learning experts at Carnegie Mellon University and fabless chip company Nvidia.

200mm wafer demand driving growth in Asia

The number of 200mm wafer fabs in the world will increase from 194 in 2017 to 203 by 2022 and 56 established fabs are looking to increase manufacturing capacity. As a result, global capacity is set to increase by 600,000 wafer starts per month to reach 6 million wafer starts per month by the end of 2022, SEMI said. Only six facilities plan to reduce manufacturing, SEMI said.

The product types driving demand are MEMS, power, logic and more general foundry.

Smart luggage adds self charging, digital scales

The team from Ebolt in Portland, Oregon, are raising money on Kickstarter for the luggage, which overcomes previous problems other smart luggage startups faced by having a 5000mAh (18.5 Wh) battery that can be removed when it goes in the hold of an aircraft. It also doesn't have the Bluetooth wireless tracking capability of other smart luggage designs that led to worries about interference.  

Evaluate nearly any amplifier in minutes with the most versatile populate-and-test EVM

The Universal Do-It-Yourself Amplifier Circuit Evaluation Module (DIYAMP-EVM) family provides engineers and DIYers with real-world amplifier circuits, enabling you to evaluate design concepts and verify simulations in minutes. The EVMs come in three industry-standard package options (SC70, SOT23, SOIC).
