Green Hills Rolls Into ESC


A new RTOS, wireless middleware and virtualization on the agenda

By David Worthington
October 1, 2007 — 
BOSTON — Green Hills Software came rolling into the Embedded Systems Conference (ESC) here last month with more on its agenda than a tea party. Like a cup of chamomile, Green Hills soothed its customers’ nerves when it announced on Sept. 19 the availability of a ThreadX-compatible real-time operating system, and revealed new middleware and an extended virtualization offering.

Green Hills was a reseller of Express Logic's ThreadX RTOS for nearly a decade, until Express Logic terminated the reseller agreement in early 2006. That June, Express Logic sought arbitration, alleging that Green Hills illegally copied the ThreadX API in the Green Hills ?-velOSity microkernel. An arbitration panel denied all of Express Logic’s claims in August of this year.

Green Hills’ customers now have two options: They may continue to use ?-velOSity, or the new ThreadX-compatible RTOS. The replacement does not require any modification of production code, said Dan Mender, Green Hills’ director of business development.

When not selling peace of mind, Green Hills was pitching security at ESC in both wireless and virtual flavors. The company released extensions to its Secure Wireless Devices Platform. The platform now includes extended Wi-Fi security, Cisco Compatible Extensions, Wi-Fi Protected Setup and reference drivers for leading Wi-Fi chipsets, and targets vertical industries. According to Mender, Integrity is certified as secure by the U.S. Federal Aviation Administration and the Food and Drug Administration, as well as the National Security Agency.

Virtualizing with Integrity
The Integrity operating system now supports Intel’s vPro processor technology, which pairs dual-core 64-bit processors with a networking chipset for networks using 802.1x or Cisco’s Network Admission Control, offering integrated hardware-based security, remote management features for PCs and virtualization capabilities.

Integrity PC works with Intel vPro to perform a secure boot in which BIOS, hardware and the Integrity kernel are measured to provide what the company calls a trustworthy execution environment. Integrity can run as the host operating system, with secure Linux or Windows partitions, without fear of cascading events, Mender explained.

Integrity can also add native applications in parallel with Linux and Windows off-the-shelf applications to the user mode, on top of Integrity.

“Point-of-sale transactions can happen through Integrity [instead of] Windows or Linux. That eliminates the possibility of corruption at the device level,” said Mender. “People aren't addressing security in virtualization.”
