Security and multi-OS consolidation for multicore processors

October 25, 2013 // By EDN
Mentor Graphics has announced its Mentor Embedded Hypervisor product for in-vehicle infotainment (IVI) systems, telematics, advanced driver assistance systems (ADAS) and instrumentation.

The Mentor Embedded Hypervisor is a small footprint Type 1 hypervisor developed specifically for embedded applications and intelligent connected devices. Developers can create high-performance systems that integrate and consolidate applications on multicore processors and make use of the ARM TrustZone. Development of new systems can be accelerated by reusing existing proprietary software and protecting intellectual property while incorporating Linux to leverage the open source ecosystem.

With the Hypervisor product, Automotive OEMs and Tier Ones now have the ability to design systems that can combine Linux, AUTOSAR, real time, and bare-metal applications and sub systems. The Mentor Embedded Hypervisor supports the Yocto Project-compatible Mentor Embedded Linux, the GENIVI-compliant Mentor Embedded Automotive Technology Platform, and will support Android, Mentor Volcano AUTOSAR software, and Nucleus RTOS. Mentor will continue to track and enable the latest versions of technologies and standards including the Yocto Project and GENIVI.

Mentor Embedded Hypervisor includes support for the ARM TrustZone, for applications requiring hardware-based partitioning of resources such as memory, crypto blocks, and keyboard/screens creating a completely separate secure world operating environment. It features a flexible device model that supports virtualised device access and direct device access for performance-critical applications and provides various mechanisms for inter-guest communications.

“Building on the advanced hardware features of ARM Cortex-A processors, embedded virtualisation enables isolation of different workloads and enhances system security,” said Keith Clarke, vice president, Embedded and Security, Processor Division, ARM.

The framework of Mentor Embedded Hypervisor is flexible, allowing it to run on single-core or multi-core processor architectures supporting asymmetric multi-processing (AMP), symmetric multiprocessing (SMP), or a combination of both. The combination of the Mentor Embedded Hypervisor and latest SoCs from silicon vendors provides an integrated solution to speed development on these emerging hardware platforms.

By using the Mentor Embedded Hypervisor embedded systems, developers can:

- Reduce test and debug times by consolidating multiple functions on a single multi-core compute platform

- Take advantage
