Modules replace USB connectors with 60GHz wireless links

By Nick Flaherty www.flaherty.co.uk

Lattice Semiconductor has launched a range of high bandwidth 60GHz wireless connector modules to support broader adoption of the technology in consumer and embedded applications. 

The Snap modules are based on Lattice’s production-proven SiBEAM 60 GHz technology to enable manufacturers to easily integrate short-range, high-speed 60 GHz wireless links into products. To simplify the design process further, Lattice included the Snap modules, which are compliant with regulatory requirements in several jurisdictions, into their Snap evaluation kit for fast prototyping and time-to-market.

“We were seeking a wireless solution that was robust, easy to integrate and wouldn’t require a lot of design support,” said Ehren Achee, CTO at SecuraShot. “Lattice’s Snap modules met all of our expectations, allowing us to develop a more rugged product that can seamlessly support the transfer of data wirelessly without delay.”

The Snap modules offer 12 Gbit/s full-duplex bandwidth at sub-frame latencies allowing it to replace physical USB connectors. By eliminating the connector, the industrial designs of new products can be optimized by making them thinner, lighter, and environment-proof, all while maintaining a robust and high-speed connection. 

To enable faster prototyping for both existing and new customers, Lattice created the Snap Evaluation Kit, which includes the modules, system design guidelines and improved de-bug tools.

“SiBEAM Snap wireless connector technology offers a unique advantage in data transfer for a variety of high volume mobile applications, such as smartphones, tablets and notebooks," said Abdullah Raouf, senior manager at Lattice. "The modules not only accelerate time to market, but will enable 60 GHz technology to be easily integrated into broader consumer and industrial products.”

The modules include fully integrated power regulation, timing, 60 GHz antenna design & regulatory compliance.

Lemonbeat aims to simplify IoT embedded software development

By Nick Flaherty www.flaherty.co.uk

Lemonbeat in Germany is launching its latest software for the rapid development of intelligent end devices for the Internet of Things (IoT).

At the heart of Lemonbeat’s Studio 2.0 IoT technology is its embedded operating system designed specifically for the Internet of Things (IoT). Integrated into the end device, the system enables users to develop individual applications by combining standardised software modules. This modular approach allows all devices, even sensors which are constrained in power or size, to act as intelligent parts of the network with the devices communicating and interacting directly by means of the use case independent Lemonbeat smart Device Language (LsDL). 

This makes gateways as well as clouds obsolete for controlling the network, says Lemonbeat, integrating edge performance with cloud analytics and device management power.

With Lemonbeat Studio 2.0, software developers and system integrators can configure Lemonbeat OS-compatible sensors and actuators without needing to write a single line of code. Using a simple point and click system, users can easily create and test intelligent behaviours and device interactions within an IoT environment.

In an IoT solution, the behaviour of the device can be modified during live operation. Lemonbeat Studio 2.0 also permits over-the-air (OTA) updates of its firmware.
A new feature in Lemonbeat Studio 2.0 is the “Lemonbeat TestSuite” plug-in. With this plug-in, users can test device configurations systematically and automatically using flexible scenarios. The test scenarios can be run in the Lemonbeat Studio interface or as a console application. The user can also integrate the configurations into existing test environments, such as Jenkins. The results can be output in XML format and exported to other systems.

The company was founded in October 2015 as a wholly owned subsidiary of innogy SE – one of Europe’s largest utility companies with many years of experience in smart home applications.

By Nick Flaherty www.flaherty.co.uk

PRO DESIGN is launching three new modules based around the Xilinx Zynq UltraScale+ FPGA to provide an embedded processing platform for the development and verification of SoC and IP designs.

The proFPGA product family is a complete, scalable, and modular multi-FPGA Prototyping solution. 
The new members of this flexible system concept are the ZU11EG, ZU17EG and ZU19EG FPGA modules, which can easily be mounted on the proFPGA uno, duo or quad motherand mixed with other proFPGA modules using Virtex-7, Virtex UltraScale, Virtex UltraScale+ or Kintex UltraScale modules. 


The latest Zynq devices combine FPGA logic with two ARM Multi-Core Processors (Quad-core ARM Cortex-A53 and Dual-core ARM Cortex-R5) and several on-board USB 3.0, Gigabit Ethernet, SATA, Display Port and debug to offer a complete embedded processing platform. Further, the boards already include an on-board DDR4 SODIMM module and a single quad SPI flash.

Nearly all SoC and ASIC designs contain some types of ARM processors. Instead of implementing these ARM cores in the FPGA and occupying important FPGA resources the user can take the proFPGA module which already has two embedded ARM multi-core processors with verified interfaces and memory. 

The module also offers a direct ARM debug interface from which the user can benefit by using the proven ARM® debug environment in combination with the proFPGA prototyping system and by putting the focus on the actual verification of his design.

The new proFPGA modules offer a total of up to 5 extension sites with 531 standard I/Os and 16 multi-gigabit transceivers (MGTs) for extending the board with standard or user specific extension boards, or for easily connecting it to other proFPGA FPGA modules to expand the capacity. The well-designed board is optimized and trimmed to guarantee best signal integrity and highest performance. It allows a maximum point-to-point speed of up to 1.2 Gbps over the standard FPGA I/Os and up to 16.3 Gbps over the MGTs.

"In today's ASIC and SoC designs you almost find always multi-core processors. The verification of these in combination with user designs and required firmware becomes essential and extremely complex. We are proud that with our new proFPGA Zynq UltraScale+ FPGA modules we can provide a complete embedded processing platform at an early stage of the development process which helps our customers to master this challenging task", said Gunnar Scholl, CEO of PRO DESIGN.

The platform comes with the proFPGA Builder software, which provides features such as advanced clock management, integrated self- and performance tests, automatic board detection, I/O voltage programming, system scan and safety mechanism and remote system configuration which only takes seconds, features which simplify the usage of the proFPGA system tremendously.

The proFPGA Zynq UltraScale+ ZU11EG, ZU17EG and ZU19EG FPGA Modules are available from February 2018.

Design cuts Bluetooth transceiver power in half

By Nick Flaherty www.flaherty.co.uk

Researchers at Tokyo Institute of Technology (Tokyo Tech) have developed a Bluetooth Low-Energy transceiver with the lowest ever power consumption for applications in the Internet of Things (IoT).

Figure 1. A photograph of the chip. The chip was designed using standard 65-nanometer CMOS technology.


When transmitting, the transceiver consumes 2.9 milliwatts (mW) and when receiving, it consumes 2.3 mW, less than half the power consumed by previous transceivers (see Table 1).

"Our research grew out of this need for connectivity," said Kenichi Okada of Tokyo Institute of Technology, Japan. "In an IoT world, trillions of devices will be used. To extend battery life and aim for maintenance-free operations, reducing power consumption is vital."

The BLE transceiver has a receiver sensitivity of -94dBm and high interference tolerance of other signals in the 3.4Gz band with the low power. It uses an all-digital phase-locked loop (ADPLL), that is less susceptible to noise compared to its analogue counterpart. The transceiver was designed in a 65nm CMOS process.

In another study focusing on ADPLL, the researchers achieved a figure of merit4 (FoM) of -246dB, one of the best obtained so far. The FoM is an important metric for evaluating the trade-off between performance and power consumption.

In future, Okada says: "The PLL could operate on just 0.65 mW, and studies are underway to reduce our transceiver's power consumption

ARM eyes up AI co-processor blocks

By Nick Flaherty www.flaherty.co.uk

Processor technology developer ARM has developed a suite of IP blocks that includes highly scalable co-processors tor machine learning (ML) and neural networks (NN).

The blocks are initially intended for integration into applications processors for mobile phones, with the first blocks available in April to early adopters. Full rollout will be in the middle of the year. 

Having the blocks scalable allows ARM to move up or down the performance curve – from sensors and smart speakers, to mobile and smart home devices as well as IoT edge devices. 

The Arm ML processor (below) is built from the ground-up, specifically for ML with over 4.6 trillion operations per second (TOPs) with a further boost of 2x-4x in effective throughput in real-world uses through intelligent data management. The power envelope is 3TOPS/W, with a 1 to 2 W profile for the chips.

The family includes the Arm Object Detection (OD) processor. It is a second-generation device, with the first generation computer vision processor already deployed in Hive security cameras. The OD processor can detect objects from a size of 50x60 pixels upwards and process Full HD at 60 frames per second in real time. It can also detect an almost unlimited number of objects per frame.

“The rapid acceleration of artificial intelligence into edge devices is placing increased requirements for innovation to address compute while maintaining a power efficient footprint. To meet this demand, Arm is announcing its new ML platform, Project Trillium,” said Rene Haas, president, IP Products Group, Arm. “New devices will require the high-performance ML and AI capabilities these new processors deliver. Combined with the high degree of flexibility and scalability that our platform provides, our partners can push the boundaries of what will be possible across a broad range of devices.”

Arm NN software, when used alongside the Arm Compute Library and CMSIS-NN, is optimized for NNs and bridges the gap between NN frameworks such as TensorFlow, Caffe, and Android NN and the full range of Arm Cortex CPUs, Arm Mali GPUs, and ML processors.

First Multi-Band and Multi-Standard Massive MIMO system

By Nick Flaherty www.flaherty.co.uk

US startup Blue Danube Systems has developed a 5G-ready Massive MIMO system that supports simultaneous beamforming over multiple frequency bands and across multiple cellular standards.

The key to the BeamCraft 600 series is the embedded software that is extendable through cloud-based intelligence to dynamically direct radio beams where mobile traffic is high. Unlike other Massive MIMO systems, they require no change to existing cell sites and are compatible with today’s smartphones and LTE nodes.

The 96-element antenna supports up to two active mid bands using 16 software configurable beams, twice the capacity of the previous generation but still within the same 14in wide form factor. Additionally, an integrated passive low-band option is also available to further conserve antenna mount positions. 

With mobile video driving ever increasing traffic demand, operators have needed to add more cell sites, acquire and deploy additional spectrum, and support multiple wireless standards resulting in more equipment per site and contributing to significant OPEX and CAPEX increases. BeamCraft 600 allows operators to gain an immediate capacity boost using existing network assets by replacing 3G/4G radio and antenna systems with a single unit thereby reducing the equipment on site – in some cases by as much as 66%. 

Blue Danube has deployed active solutions in 3 mid bands to date (AWS, PCS, DCS) and will trial the multi-band BeamCraft 600 in 2Q’18. Additional products supporting higher frequency bands including TDD will be available in 2H’18.

“Blue Danube’s portfolio of Massive MIMO products enables operators to flexibly customize RF energy to optimize capacity, coverage and cell edge performance.” said Mark Pinto, CEO & President of Blue Danube Systems. “Our 5G-ready architecture allows beam-based network management leading to virtualization of the network RF functions. By avoiding the rigidity imposed by other radio architectures, we are enabling a completely flexible RAN ecosystem.”

“With FDD representing at least 85% of the global commercial networks, mid band FDD Massive MIMO solutions will be critical as operators transition to 5G,” said Julian Bright, analyst at Ovum. “The vast majority of the world’s leading operators have multiple 3G and 4G LTE bands in this frequency range. Blue Danube’s multi-band solution offers a compelling upgrade option for current networks, unlocking the potential of operators’ most valuable FDD spectrum asset.”

Blue Danube Systems is a privately held start-up backed by Sequoia Capital and Silver Lake along with other investors including AT&T. 

Transmit-only Bluetooth chip boosts beacon battery life

By Nick Flaherty www.flaherty.co.uk

Asahi Kasei Microdevices (AKM) has developed a transmit-only Bluetooth Low Energy (BLE) chip that enables designs of beacons with longer battery life with lower embedded software development requirements.


BLE beacons are used in various applications such as monitoring systems, loss prevention devices, employee attendance management, and information guidance to smartphones in shops or exhibitions. However there were only BLE SoCs which support both transmitter and receivers that require higher levels of software development.

The AK1594 allows a BLE beacon to be developed using the initial settings and transmission data to the internal EEPROM as there is no microcontroller and no receive path. The device achieves best in class low power consumption in the field and a maximum +6dBm (typ.) output transmission with 9.1uA (typ.) power consumption at 0dBm and an advertising interval of 1sec. 

This opens up the possibility of self powerd beacons using energy harvested either from solar cells or from the body in wearable systems.
 
It also provides security protection for advertising channel packet using the AES128 encoding that  prevents tracking or cloning of the beacon for spoofing attacks. The various switching actions control transmitter power, interval and powering the transmitter.

Samples are available now and the chip is being used in beacons by Houwa Design Systems of Japan.

Intel launches Xeon chip for edge computing

By Nick Flaherty www.flaherty.co.uk

There is a perception that using the x86 architecture means there is code compatibility all across the chain of the Internet of Things. This after all was behind the Pentium-based Quark processor for wearables and IoT node designs launched back in 2013.

Now Intel has launched a multi-core processor that brings the Xeon architecture down from the data centre to the edge of the network.

The Xeon D-2100 processor is designed for edge applications and other network applications constrained by space and power. The chips will have from 4 to 18 Skylake-server cores and up to 512 GB of addressable memory alongside an integrated Platform Controller Hub (PCH), integrated high-speed I/O and up to four integrated 10 Gigabit Ethernet ports with a thermal design point (TDP) of 60 watts to 110 watts. 

The point of moving these devices ot the edge is that they can run the same instruction set as more robust Intel Xeon Scalable processors to provide software consistency and scale from the data centre. These include Intel's latest Advanced Vector Extensions 512 (AVX-512) thata are used in software for analytics, compute-intensive applications, cryptography, and data compression.
QuickAssist Technology is available as a hardware option up-to 100 Gbps, for growing cryptography, encryption, and decryption workloads for greater efficiency while delivering enhanced transport and protection across server, storage, and network infrastructure.

There is also hardware Virtualization Technology for dynamic provisioning of services as communication service providers extend network functions virtualization (NFV) to the network edge.
Intel's Platform Storage Extensions enable smarter and more cost-effective storage solutions through integrated technologies that accelerate data movement, protect data, and simplify data management while Advanced Encryption Standard New Instructions (AES-NI) accelerates data encryption and decryption for secure websites.

“To seize 5G and new cloud and network opportunities, service providers need to optimize their data center and edge infrastructures to meet the growing demands of bandwidth-hungry end users and their smart and connected devices,” said Sandra Rivera, senior vice president and general manager of the Network Platforms Group at Intel. “The Intel Xeon D-2100 processor allows service providers and enterprises to deliver the maximum amount of compute intelligence at the edge or web tier while expending the least power.”

This will help communications service providers CoSPs offer multi-access edge computing (MEC), which allows software applications to tap into local content and real-time information about local-access network conditions, reducing mobile core network of network congestion. This can enable designs from 5G-connected cars, smart stadiums, and retail and medical solutions.




It can be used for edge storage, Content Delivery Networks (CDNs), enterprise SAN and NAS storage, midrange routers, network appliances, security appliances, wireless base stations and embedded midrange IoT usages, among others.
