Autotalks introduces first VLSI for vehicle-to-vehicle communication

Autotalks, a fabless semiconductor company developing a novel solution for vehicle-to-vehicle and vehicle-to-infrastructure communication, recently released the first VLSI (very large scale integration) chip for vehicle-to-vehicle communication.

Dubbed “CRATON”, the VLSI is the result of several years of working closely with leading OEMs and Tier 1s, and was developed based on the performance and quality requirements of vehicle-to-vehicle communication safety applications. Autotalks showcased CRATON at the 19th ITS World Congress, Vienna.

Autotalks also offers PLUTON, an advanced dual channel 5.9GHz transceiver, with 700MHz band support for worldwide operation. PLUTON is manufactured by Altis Semiconductors, and will be AEC-Q100 qualified. Together with PLUTON, CRATON forms a comprehensive, automotive grade, VLSI solution enabling OEMs’ deployment of vehicle-to-vehicle systems in the 2015 model year.

CRATON includes a dual-channel modem that can concurrently support two independent channels or one channel with optimal antenna diversity. Longest communication range is measured for fast moving vehicles and in presence of obstructions.

For security, all received packets are authenticated at minimal and fixed latency. Alternative solutions are obliged to select vehicles for authentication, potentially missing safety alerts. Those solutions store packets inside a FIFO before authentication, significantly increasing latency.

CRATON supports worldwide operation, following IEEE802.11p, IEEE1609, ETSI ITS and Japan ARIB STD-T109 specifications. Autotalks provides a complete communication software stack for all geographies, along with rich and flexible API for application development.

CRATON is manufactured by Fujitsu Semiconductors, and is scheduled to obtain AEC-Q100 qualification. CRATON supports wide temperature range of -40 °C to +85 ºC. CRATON samples will be made available to selected customers in December 2012. CRATON development platform will be available at early 2013. The platform is delivered with applications for real-time performance measurement and analysis to simplify field tests.

Sonics, Inc., a supplier of system IP for cloud-scale system-on-chips (SoCs), announced that Autotalks is using the Sonics Network for AMBA (Advanced Microcontroller Bus Architecture) Protocol (SNAP) to power the design of CRATON.

(The AMBA protocol is an open standard, on-chip interconnect specification for the connection and management of functional blocks in a System-on-Chip (SoC).)

Sonics’ SNAP empowers Autotalks designers to aggressively drive innovation in the automotive technology market, while still upholding our commitment to high-quality vehicle-to-vehicle communication. The intuitive user interface greatly increased productivity, enabling us to bring CRATON to market on schedule, as the first VLSI for vehicle-to-vehicle communication. Thanks to SNAP’s improved AMBA performance and low latency architecture, we were able to achieve CRATON’s superior performance for the demanding vehicle to vehicle software solution requirements.

—Onn Haran, CTO, Autotalks

As the number of IP cores continues to increase in embedded SoCs, current multilayer bus structures must evolve beyond the complex design approach, SOnics says. Fully compliant with the AMBA specification, SNAP allows Autotalks to simplify processes, through a reusable platform with universal connectivity on the interconnect matrix, allowing designers to mix new and legacy IP cores.
