2013-04-16 11:38:42 - NVIDIA and OpenSynergy present jointly developed solution

Berlin, Germany, 22 February 2013. At embedded world 2013 OpenSynergy and NVIDIA are using a joint demonstrator to present a head unit and an instrument cluster integrated onto a single quad-core NVIDIA® Tegra® 3 processor, NVIDIA’s flagship system-on-chip (SoC) automotive-grade solution. The virtualization technology found in COQOS, OpenSynergy’s standards-based software platform, makes optimum use of this processor, allowing several CPU-intensive systems to be embedded onto the chip. The demonstrator can be seen from 26-28 February 2013 at the exhibition center in Nuremberg, Germany (Hall 5, Stand 241).
Automobile manufacturers and their suppliers are faced with the challenge of having to integrate an increasing number of functions onto just a few electronic control devices. Graphic-intensive software systems in particular require ultrahigh-performance

processors to achieve this. These include head units, digital instrument clusters, rearview cameras, or TopView systems, for example.
Another challenge is how to integrate software systems with the widely different requirements in terms of functional safety, data security, and real-time performance, as well as how to intelligently divide the processor resources between critical and less critical applications. Resources include the individual cores of the multiprocessor system, the graphics hardware, and the interfaces that link the electronic control devices to the vehicle's electrical system or to external services. There is also the risk that the vehicle’s network could come under attack from malicious software when connecting to the Internet.
COQOS on NVIDIA Tegra offers carmakers a solution to meet all of these challenges. The Tegra 3 processor includes, among other things, a graphic processor specially developed for high-speed, interactive performance. NVIDIA also delivers the driver and its UI Composer software tool chain for the joint solution, the latter of which is used to design and optimize graphics intensive applications such as digital instrument clusters and infotainment systems. The demonstrator will showcase numerous examples of HMIs developed using the UI Composer on the instrument cluster/head unit display.
COQOS uses the Tegra GPU to simultaneous integrate and operate two graphic-intensive software systems — the head-unit and instrument cluster. Likewise, COQOS makes it possible to meet the requirements in terms of functional safety, security, and real-time performance when vastly different guest operating systems are integrated onto a single Tegra SoC. The software platform is based on a hypervisor that creates logical partitions. Virtualized operating systems like Linux and time-critical
applications that run without an additional operating system can be placed on these partitions. COQOS also includes an AUTOSAR environment that runs in a separate partition.

The flexible mapping of partitions to the processor core is a feature unique to COQOS on multicore processors such as Tegra. This allows, for example, guest operating systems that require high computing power to access multiple cores. Conversely, several deterministic partitions are able to share a single core. This dynamic assignment of resources allows COQOS on Tegra to make optimum use of the processor’s computing power.
To illustrate how effectively COQOS and Tegra work together, the demonstrator will showcase a head unit and instrument cluster integrated onto a single Tegra processor. Both functions are 3D accelerated and, hence, graphic-intensive applications.
Stefaan Sonck Thiebaut, General Manager of OpenSynergy, invites you to come and see the demonstrator in action at the exhibition. “With our newly developed solution we have opened the door to a wide range of new applications. It will now be possible to run more and more graphic-intensive systems in vehicles on fewer and fewer electronic control devices.”
