French start-up Trango Systems is demonstrating ARM926 and XScale versions of its hypervisor technology at the ARM Developers' Conference this week in Santa Clara, Calif. The Trango Hypervisor divides a single core into multiple virtual processors, enabling multiple execution environments to run securely, side-by-side, the company says.

Trango's Hypervisor demo shows a number of single processor cores concurrently running, and showcases the product's new capability of supporting Windows CE, in addition to Linux and various RTOSes (real-time OSes). Specifically, the company says it is demonstrating:

• A Linux and Qtopia stack, for operator interfaces
• An unspecified RTOS for use in modems
• Windows CE, for games and other applications

The key benefit of virtualization, Trango says, is the ability to build secure and scalable platforms on a single processor core. The virtual machines (VMs) are completely isolated from one another, resulting in a secure environment for services such as DRM, secure download, device management, or mobile payments.

Trango marketing manager Andry Ramiandrasoa stated, “Our technology to host, securely, multiple execution environments and software stacks is one major competitive advantage of Trango hypervisor in the embedded virtualization market. Isolation of rich OSes, and trusted services, like DRM, firmware update, or payment applications, is highly critical for operators to deploy new services on next generation wireless and multimedia handsets.”

Availability

The Trango Hypervisor currently supports ARMv5, MIPS32, and MIPS64 architectures, with ARMv6 support scheduled for release in Q1 of 2007. Supported operating systems currently include Linux, Windows CE 5.0, eCos, and MicroC/OS, among others.
