Multicore Microcontrollers for IoT and audio

XMOS has, from its base in Bristol, England, been quietly building up its business of creating a new force in the embedded market. The company has been shipping the xCore multicore microcontrollers into a wide range of companies around the world, and has built a particularly strong position in audio. Last summer it was announced that the company had raised £26.2 million from Robert Bosch Venture Capital, Huawei Technologies, and Xilinx.

Now it is announcing a new generation of  xCORE – xCORE 200, and a product specifically for the high resolution audio market – xCORE-Audio

The xCORE -200 is targeted at the Internet of Things, with Gigabit Ethernet joining USB 2.0 and high performance general IO, improved performance (2000 MIPS in the launch device), and increased memory. A new development , upgraded tool suite and improved libraries. Code written for earlier xCORE products will run on the xCORE-200. Deterministic real-time operations make the family suitable for a wide range of data acquisition, networking, HMI and other applications.

The success that XMOS has in audio provided the impetus for two  families optimised for this field. The xCORE-Audio/ Hi-Res is for consumer audio and video, including stero high resolution headphone amplifiers and the xCORE-Audio/Live addresses prosumer and professional audio, such ads DJ kits, mixing, and conferencing. They both work with a range of operating systems, support a variety of audio formats and interfaces, including USB type C.

DSP support in the xCORE-Audio/ Hi-Res is aimed at applications like surround sound and karaoke while that in the xCORE-Audio/Live is aimed at audio mixing and post-processing pipelines. And the company points out that pricing starts at less than $2.00 in high volume.

An in-depth report on this will follow.

Demo: Inuitive NU4000 SoC with ARC EV Processor Running SLAM and CNN

Sponsored by Synopsys

See Inuitive’s NU4000 3D imaging and vision processor in action. The SoC supports high-quality 3D depth processor engine, SLAM accelerators, computer vision, and deep learning by integrating Synopsys ARC EV processor. In this demo, the NU4000 demonstrates simultaneous 3D sensing, SLAM and CNN functionality by mapping out its environment and localizing the sensor while identifying the objects within it.

The Cryptography Handbook

Sponsored by Maxim Integrated

The Cryptography Handbook is designed to be a quick study guide for a product development engineer, taking an engineering rather than theoretical approach. In this series, we start with a general overview and then define the characteristics of a secure cryptographic system. We then describe various cryptographic concepts and provide an implementation-centric explanation of physically unclonable function (PUF) technology. We hope that this approach will give the busy engineer a quick understanding of the basic concepts of cryptography and provide a relatively fast way to integrate security in his/her design.

PiezoListen: A New Kind of Speaker for New Applications

Sponsored by Mouser Electronics and TDK

Until recently, putting speakers into extremely space-constrained designs was a daunting challenge. Now, however, advances in piezo speakers bring remarkable performance to ultra-small ultra-thin speakers. In this episode of Chalk Talk, Amelia Dalton chats with Matt Reynolds of TDK about PiezoListen - a whole new kind of high-performance multilayer piezo speaker.
