Technology Demonstration Illustrates Innovative Solution for Defense and Avionics Data Systems

SANTA CLARA, CA–October 22, 2007–ALT Software, DiSTI, Green Hills Software and RTI will demonstrate at MILCOM (October 29-31, booth #305, Orlando, FL) a technology integration that promises to radically change the design and implementation of real-time, safety-critical distributed systems for defense and aerospace applications. The combination of these firms’ technologies provides a robust solution for mission-critical data distribution and display.

The demonstration will consist of a real-time avionics display rendered on a Freescale Media5200 reference platform and controlled remotely from a Windows XP system. The Media5200 target board is running the Green Hills Software INTEGRITY real-time operating system (RTOS) with output to a dynamic avionics human-machine interface (HMI) created using DiSTI GL Studio and powered by ALT Software OpenGL graphics drivers. Remote-control and data access across the network leverages RTI Data Distribution Service middleware. The result is a real-time integrated avionics network that represents the potential for next-generation designs in the cockpit for remotely piloted vehicles as well as other defense and aerospace applications.

The use of RTI Data Distribution Service provides a robust and data-driven network architecture that ensures the real-time availability of data anywhere on the network. RTI Data Distribution Service, an implementation of the Object Management Group (OMG) Data Distribution Service for Real-Time Systems (DDS) standard, employs application-level Quality-of-Service policies and an extremely efficient discovery protocol that automatically detects network failure and reconnects without intervention when service is restored.

“The era of point-to-point avionics systems with single-purpose displays and hard-wired connectivity is over,” explained Stan Schneider, founder and CEO of RTI. “The combination of a data-centric network model with a high-performance

RTOS and fast, high-quality graphical HMIs offers an innovative solution package for demanding data-availability, processing and display applications.”

Green Hills Software’s INTEGRITY RTOS drives the PowerPC target board running the HMI display and provides a highly reliable partitioned environment for real-time processing. INTEGRITY prohibits errant code from entering the kernel and disrupting the system, thus achieving high levels of safety and security.

“INTEGRITY has a distinguished reputation in defense and avionics systems where real-time response, safety and reliability are the most important considerations,” commented David Kleidermacher, chief technology officer, Green Hills Software. “Combined with a data system on a network, INTEGRITY is a superb choice for driving an avionics or weapons system when failure is not an option.”
