Automotive Electronics ADAS surround view development kit Renesas’ ADAS Surround View Kit is intended to enable quick time to market for automotive system manufacturers; the kit is an extension of Renesas’ ADAS Starter kit itself designed to be used in a wide spectrum of applications. The ADAS Surround View Kit combines automotive cameras from Integrated Micro-electronics Inc. and multiple high-speed gigabit multimedia serial links (GMSL) from Maxim Integrated Products, on a miniature automotive chassis. This eliminates the need for system manufacturers to source and set up all these specific automotive components themselves for their surround view development. The kit also provides a 2-channel CAN interface and a gigabit Ethernet connector interface for in-car applications, where the model chassis is not used. Once connected via an on-board extension connector to the already available ADAS Starter Kit, the ADAS Surround View Kit provides a high level of processing performance to system manufacturers. It is based on the Renesas R-Car H2 SoC (System-on-Chip), which is capable of delivering more than 25,000 DMIPS and providing state-of-the-art 3D graphics capabilities and powerful vision processing cores. The R-Car H2 SoC supports up to four independent input HD camera channels, allowing implementation of 360° camera views and object recognition.

They add up to the company’s sound effects for general car audio and infotainment systems, including cabin noise reduction. Arkamys www.arkamys.com 2.3 Mpixel automotive image sensor carries ASIL B qualification ON Semiconductor is sampling its next generation ADAS (advanced driver assistance systems) automotive image sensor with LED Flicker Mitigation and ASIL B support. ON Semi is seeing a marked increase in the number of image sensors deployed per car in ADAS functions. Its most recent introduction provides, among other features, flicker reduction. This is intended to eliminate, directly at the sensor, the strobing effect that can occur when the image sampling cycle ‘beats’ with the pulsed waveform driving LED tail-lights in other vehicles, or illuminated speed-limit signs. The sensor also has a high dynamic range, substantially exceeding that of the human eye; and it is also the only sensor in its applications space, ON claims, to have ASIL B support. Using a 4-exposure capture cycle to achieve HDR (high dynamic range) the device can reach frame rates of up to 40 fps, and dynamic range of 120 dB. The LED Flicker Mitigation (LFM) technology in the sensor eliminates high frequency LED flicker from traffic signs and vehicle LED lighting and allows Traffic Sign Reading algorithms to operate in all light conditions. The AR0231AT has a 1 / 2.7 in. (6.82 mm) optical format and a 1928 (horizontal) x 1208 (vertical) active pixel array. It uses 3.0 micron Back Side Illuminated (BSI) pixel with ON Semiconductor’s DR-Pix technology, which offers dual conversion gain for improved performance under all lighting conditions. It captures images in linear, HDR or LFM modes, and offers frame-to-frame context switching between modes and has multiple data interfaces including MIPI, parallel and HiSPi. AR0231AT occupies an 11 x 10 mm iBGA-121 package and engineering samples are available now. ON Semiconductor www.onsemi.com Digital instrument cluster is safety certifiable Mentor Graphics’ automotive safety certifiable digital instrument cluster solution enables safety-critical driver information to be displayed simultaneously with rich 3D graphics on a single instrument cluster display. The software architecture is implemented on a multi-core and even on single-core System-on-Chip, and features very fast boot time. This new solution addresses a key problem for the automotive OEMs: how to migrate safety-critical driver information to full-featured, graphically rich digital instrument clusters and comply with safety standards including ISO 26262, without pushing up hardware or safety certification costs. Automotive OEMs today design digital instrument clusters that include graphical information relating to essential warnings from the vehicle, such as icons notifying the driver of brake, engine or tire problems. The new solution, which is compatible with safety-certified Nucleus RTOS and Mentor’s automotive-qualified Linux solutions, allows safety-critical and non-critical information to be displayed simultaneously on the same display, while maintaining isolation of safety-related functions to comply with ISO 26262 safety standards. The solution enables car makers to reduce costs because the system is built on pre-certified components such as the Nucleus SafetyCert RTOS, resulting in minimization of the number of lines of new code to be safety certified. It reduces silicon cost because the solution runs on a single SoC, or even a single core, and makes efficient use of available CPU resources.
