Sensor does not need soldering or programming says TDK

For intelligent multi-sensor monitoring and remote data collection, SmartSense from TDK can be used in a diverse range of IoT applications outputs via Bluetooth Low Energy and wi-fi.

The sensor module can be used ‘out-of-the-box’ and with no need for soldering, programming or mechanical modifications, to deliver sensor data (both raw and intelligent) wirelessly in smart homes and appliances and wellness monitoring, says TDK.

SmartSense can be used in smart doors, robotic vacuums, asset monitoring, patient activity monitoring, HVAC filtering and air mouse monitoring. SmartSense integrates TDK’s IMU, magnetometer, pressure, temperature, and ultrasonic sensors with high-precision algorithms. The module also provides autonomous SD Card data logging for applications deriving value from large data volumes.

SmartSense integrates TDK’s inertia measurement unit (IMU), magnetometer, pressure, temperature, and ultrasonic sensors with high-precision algorithms. The list of algorithms will be expanded in the coming months, based on emerging market requirements, confirms TDK.

The module serves as a prototyping platform by enabling OEMs to gain application insights, signatures and environment variations. For example, a company manufacturing patient activity monitors needs both high-resolution and low-noise IMU data, as well as meaningful algorithmic information about patients’ gait, body posture and balance. SmartSense provides all this information, enabling OEMs to quickly prototype their products while working closely with TDK to get secure access to medical algorithms and IMUs.

TDK will demonstrate SmartSense at CES booth 11448 at CES, Central Hall (LVCC), Las Vegas Convention Center, 7 to 10 January 2020.

Bluetooth LE Audio codec is first for power-sensitive audio says Synopsys

Optimised for Synopsys’ ARC processor IP, a low complexity communication codec (LC3) has been developed by Synopsys with the Fraunhofer Institute for Integrated Circuits (IIS).

The new codec is designed to comply with the forthcoming Bluetooth LC3 audio codec specification and is optimised to deliver high-quality audio and voice playback in battery-powered devices incorporating ARC EM and HS DSP processors, says Synopsys.

It has been added to Synopsys’ portfolio of DesignWare ARC audio codecs and post-processing software supporting popular audio standards. It also extends Synopsys’ DesignWare Bluetooth Low Energy IP offering.

The 32-bit DesignWare ARC EM and HS DSP processors are based on the scalable ARCv2DSP Instruction Set Architecture (ISA) and integrate RISC and DSP capabilities for a flexible processing architecture. The ARC EM DSP processors offer low power and what is claimed to be industry-leading performance efficiency while the multi-core-capable ARC HS DSP processors combine high-performance control and high-efficiency digital signal processing. All ARC processors are supported by the ARC MetaWare Development Toolkit, which includes a library of DSP functions to allow software engineers to rapidly implement algorithms from standard DSP building blocks. ARC processors and the LC3 codec can be combined with Synopsys’ Bluetooth 5.1-compliant DesignWare Bluetooth Low Energy IP to deliver power-efficient, high-quality wireless audio capability for smart IoT and other Bluetooth-enabled devices.

The LC3 codec is an important feature of the Bluetooth LE Audio specification to be released by the Bluetooth Special Interest Group (SIG) that enables system on chip (SoC) designers to efficiently implement high-quality voice and audio streaming in a wide range of applications, including mobile, wearables, and home automation.

The LC3 codec for ARC processors is based on an implementation by Fraunhofer IIS that is designed to meet Bluetooth SIG requirements. The LC3 codec, running on ARC EM and HS DSP processors, allows designers to rapidly integrate a complete, pre-verified hardware and software solution for voice and speech processing into Bluetooth-enabled devices requiring minimal energy consumption, explains Synopsys.

“The rapid growth of wearable devices requiring high-quality Bluetooth audio streaming is driving the need for power-efficient processor IP with DSP capabilities that can meet intensive computation requirements of voice and audio applications. Those applications require an optimised codec providing state-of-the art voice and audio quality at minimum computational complexity,” said Manfred Lutzky, head of Audio for Communications at Fraunhofer IIS. “By porting the LC3 codec to the DSP-enhanced ARC processors, Synopsys is enabling customers to quickly implement LC3 codec functionality in their low-power SoCs. We look forward to continuing our collaboration with Synopsys so that the LC3 codec for ARC processors continues to incorporate the latest updates,” he added.

“The fact that the LC3 codec can provide very high-quality audio even at low bit rates makes it a key feature of the upcoming LE Audio standard,” said Mark Powell, chief executive officer of the Bluetooth SIG. “

John Koeter, senior vice president of marketing for IP at Synopsys, said: “Designed to process high-quality audio streams and deliver superior sound, the LC3 codec for ARC processors provides designers with a certified codec that reduces the integration time and testing required to deliver superior quality audio for Bluetooth streaming applications.”

The Bluetooth LC3 codec is available now from Synopsys with DSP-enhanced ARC EMxD and HS4xD processors.

i.MX applications processor has NPU for advanced ML at the edge

The latest member of NXP’s EdgeVerse portfolio has been launched at CES in Las Vegas (7 to 10 January). The i.MX 8M Plus heterogeneous application processor is the first i.MX family to integrate a dedicated neural processing unit (NPU) for advanced machine learning (ML) inference at the industrial and IoT (Internet-of-Things) edge.

The NPU delivers 2.3Toperations per second and is combined with a quad-core Arm Cortex-A53 sub-system running at up to 2GHz. There is also an independent real-time sub-system with an 800MHz Cortex-M7, an 800MHz audio DSP for voice and natural language processing, a dual camera image signal processors (ISP) and a 3D GPU for rich graphics rendering. The i.MX 8M will enable edge devices to make intelligent decisions locally by learning and inferring inputs with little or no human intervention, says NXP. Target applications are people and object recognition for public safety, industrial machine vision, robotics, hand gesture, and emotion detection with natural language processing for seamless human-to-device interaction with fast response time and high accuracy.
The applications processor is based on 14nm LPC FinFET process technology. The i.MX 8M Plus can execute multiple, highly-complex neural networks simultaneously, these include multi-object identification, speech recognition of 40,000+ English words and medical imaging. The NPU is capable of processing Mobilenet, a popular image classification network at over 500 images per second, adds NXP.
Developers can off-load machine learning inference functions to the NPU, allowing the Cortex-A and Cortex-M cores, DSP and GPUs to execute other system-level or user applications tasks. The vision pipeline is anchored by dual integrated ISPs that support two high-definition cameras for real-time stereo vision or a single 12Mpixel resolution camera and includes high dynamic range (HDR) and fisheye lens correction for real-time image processing in surveillance, smart retail applications, robot vision and home health monitors.
For voice applications, the i.MX 8M Plus integrates a HiFi 4 DSP that enhances natural language processing with pre- and post-processing of voice streams. The Cortex-M7 domain can be used to run real-time response systems while the applications processor domain executes complex non-real-time applications. It reduces overall system-level power consumption by turning off the application processor domain while keeping only the Cortex-M domain alive for wake word detection. For advanced multimedia, and video processing, the processor can compress multiple video feeds using the H.265 or H.264 HD video encoder and decoder for cloud streaming or local storage, 3D/2D graphics, and Immersiv3D audio with Dolby Atmos and DTS:X.

In industrial scenarios, it can be used in machines that inspect, measure, precisely identify objects and enable predictive maintenance by detecting anomalies in machine operation. It can also support making the factory human machine interfaces (HMIs) more intuitive and secure by combining accurate face recognition with voice/command recognition and gesture recognition. The i.MX 8M Plus integrates Gigabit Ethernet with time sensitive networking (TSN), which combined with Arm Cortex M7 real-time processing provides deterministic wired network connectivity and processing, NXP explains.
Other features for industrial use are error correction code (ECC) for internal memories and the DDR interface.
The family is expected to be qualified to meet the stringent industrial temperature range (-40 to +105 degrees C ambient).

Jacinto 7 processors have functional safety features to advance ADAS 

Deep learning capabilities and advanced networking characterise the Jacinto 7 processor platform that Texas Instruments launched at CES. The first two automotive devices in the platform, TDA4VM processors for advanced driver assistance systems (ADAS) and DRA829V processors for gateway systems, include specialised on-chip accelerators to segment and expedite data-intensive tasks, like computer vision and deep learning.

The TDA4VM and DRA829V processors also incorporate a functional safety microcontroller, making it possible for original equipment manufacturers (OEMs) and Tier-1 suppliers to support both ASIL-D safety-critical tasks and convenience features with one chip, points out Texas Instruments. They share a single software platform, to reduce system complexity and cost as developers can reuse their software investment across multiple vehicle domains.

The TDA4VM processor offers on-chip analytics combined with sensor pre-processing, enabling OEMs and Tier-1 suppliers to support front camera applications using high-resolution 8Mpixel cameras to see farther and add enhanced features, such as drive assist. They are also capable of simultaneously operating four to six 3Mpixel cameras while also fusing other sensing modalities such as radar, lidar and ultrasonic on one chip, adds Texas Instruments. This multi-level capability enables TDA4VM to act as the centralised processor for ADAS. It also enables the critical features for automated parking, like surround view and image processing for displays and enhanced vehicle perception.

The DRA829V processor integrates the computing functions required for modern vehicles. It is believed to be the first in the industry to incorporate a PCIe switch on-chip in addition to an eight-port gigabit time sensitive network (TSN) -enabled Ethernet switch for faster computing functions and communications throughout the vehicle.

It also supports ASIL-D safety-critical and non-safety-critical operations and enables  OEMs and Tier-1 suppliers to support mixed-criticality applications on one device. Higher bandwidth on-chip also allows developers to manage software development and validation in vehicles, for more dynamic updates and upgrades.

Pre-production TDA4VM and DRA8329V processors are available now, together with Jacinto 7 processors development kits and TDA4VMXEVM and DRA829VXEVM evaluation modules.

Volume production is expected to be available in the second half of 2020.
