GPU IP advances ADAS with safety-critical graphics, says Imagination

Claimed to be the most advanced automotive GPU IP created to date and the industry’s first licensable IP that is ISO 26262-capable, XS has been announced by Imagination Technologies.

The XS GPU for automotive will enable ADAS acceleration and – being ISO 26262-capable – safety-critical graphics workloads, says the company.

Safety critical graphics and compute capabilities are required for surround view, digital dashboards and ADAS. The XS design employs a new safety architecture with mechanisms for compute and graphics delivering up to two times higher performance for critical workloads. The result is rich, high-performance graphics that are functionally safe, says Imagination.

According to the company, the XS class is the industry’s first GPU class designed for safety-critical graphics applications (i.e., where the GPU is responsible for critical tasks such as digital dashboards, surround view and camera systems).

As the industry’s first ISO 26262-capable GPU IP, OEMs, Tier 1s and semiconductor vendors can integrate the IP confident that ISO 26262 is achieved, adds Imagination.

The safety architecture contains patent pending technology that enables Imagination to secure and verify the correct execution and delivery of data from the GPU to meet functional safety requirements. XS includes hardware mechanisms that carry out safety-critical workloads across compute and graphics.

 The architecture incorporates new capabilities and safety mechanisms, such as Tile Region Protection, in addition to existing features such as virtualisation. These hardware features mean they can be employed without a performance penalty.

This a significant step forward for automotive GPUs and autonomous vehicles.”

Imagination supplies GPUs for automotive SoCs for use in digital dashboards, surround view and infotainment systems. The UK-based company creates silicon and software IP based on graphics, compute, vision and AI and connectivity technologies.

In 2017, Imagination Technologies was acquired by Canyon Bridge, a global private equity investment fund.

STMicroelectronics adds Zigbee 3.0 support for wireless microcontrollers

Based on Zigbee PRO protocol stacks, Zigbee 3.0 has been added to the STM32WB55 wireless microcontrollers. The company says that STM32 developers can leverage the interoperability and power-saving features of Zigbee to enhance networking for projects such as home automation, smart lighting, smart building, and broader IoT connectivity.

Zigbee 3.0 unifies the features of Zigbee specifications for consumer and industrial applications. Consumer and internet brands have elected to choose Zigbee connectivity for smart home products.

ST’s Zigbee 3.0 software for STM32WB55 includes the Exegin Zigbee PRO protocol stack, which is provided free of charge, and delivered and fully supported by ST. The stack is used in Exegin products certified as Zigbee Golden Units and is approved as a reference stack for use by test laboratories. ST supports 46 Zigbee 3.0 clusters to establish the capabilities of devices. Another21 clusters support legacy products.

STM32WB55 microcontrollers also support Thread and Bluetooth 5.0, with over the air (OTA) update capability. There are 10 STM32WB55 variants, in a choice of package styles and flash density from 256kbyte to 1Mbyte. The company has announced that it will introduce further variants in Q3.

Devices feature the Arm Cortex-M4 with floating point unit, DSP instructions and a memory protection unit (MPU) that enhances application security. Arm Cortex-M0+ co-processor is dedicated to managing the integrated IEEE 805.15.4 radio. The microcontroller’s cyber protection features ensures real time, low layer operations run smoothly without compromising application execution. The RF transceiver has a link budget of 106dB, to ensure reliable connections over distance.

The STM32WB55 devices are based on patented low power microcontroller technologies and integrate features such as radio balun circuitry. These characteristics are designed to help designers meet tight power and size constraints in a range of IoT and wearable devices. There are rich analogue and system peripherals, as well as cyber-protection, adds ST, and ID features including secure firmware installation (SFI), customer key storage, hardware public key authority (PKA), and cryptographic accelerators. Capacitive touch and LCD controllers simplify user-interface integration.

The Zigbee 3.0 software is now included in the STM32CubeWB MCU package, which provides embedded software including low-layer (LL) application programming interfaces (APIs) and hardware abstraction layer (HAL) drivers for STM32WB microcontrollers, as well as Bluetooth 5.0, Mesh V1.0, and Thread libraries, FreeRTOS kernel, FatFS file system and the STMTouch capacitive-sensing library.

The STM32Cube ecosystem includes the STM32CubeMonitor-RF for RF testing and STM32CubeMX for device configuration and code generation.

Software enables 5G NR to operate independently of 4G networks

Software developed by Ericsson is claimed to represent a milestone for 5G New Radio (NR) general availability.

The software enables 5G NR to operate independently of 4G networks, leading to higher levels of performance and new capabilities, says the company. Standalone 5G NR delivers faster connection times and instant access to wide bands to offer a better user experience.

The standalone 5G NR software can be used by communications service providers to operate 5G NR without the need for signalling support from an underlying LTE network. This will allow service providers to add 5G NR to existing 4G sites with a simpler architecture, or deploy 5G independently in new areas such as factories, to support enterprise applications and services. All Ericsson Radio System equipment deployed since 2015 can support Standalone 5G NR capabilities with a software installation.

5G networks have been deployed in non-standalone (NSA) mode where the underlying 4G network layer supported the necessary signalling. Standalone 5G NR delivers faster network connection times, simpler mobility management and immediate access to wide 5G bands, explains Ericsson.

Per Narvinger, head of product area networks, Ericsson, says: “Over the past year, we have worked closely with many customers to successfully deploy non-standalone 5G. These 5G networks have enabled higher data speeds and new use cases”. He added that making the software to support standalone 5G NR networks generally available, will enable applications that require low latency, such as augmented and virtual reality (AR/VR), smart factories and connected vehicles.

With a super-fast response time, a standalone 5G NR device can connect six times faster to a standalone 5G network than a device operating in NSA mode, confirms Ericsson.

The software is available now. Ericsson’s partners, T-Mobile and Telstra have trialled the standalone 5G NR software on their commercial networks.

Abdul Saad, CTO, T-Mobile, says: “Standalone 5G is the next important step for wireless connectivity, with the potential to unleash a whole new range of future transformative applications”.

Channa Seneviratne, network and infrastructure engineering executive, Telstra, says: “As the first in Australia to enable Standalone 5G, we appreciate the significance of this milestone and how 5G will be a key enabler to create new opportunities for an even better user experience and new business models.”

Standalone 5G devices are expected to become available later in 2020.

JS Pan, general manager, wireless communication system and partnership, MediaTek, said the software “will help accelerate the roll-out of standalone 5G NR, which promises to significantly boost overall 5G network performance, furthering our efforts to bring consumers a superior mobile experience”.

With the general availability of standalone 5G NR software on low and mid bands, Ericsson now offers end-to-end standalone 5G, supported by the Ericsson 5G Core (5GC) and the company’s diverse 5G radio portfolio.
