San Diego, CA, April 23, 2007 — Aonix®, a provider of solutions for safety- and mission-critical applications, announced that ObjectAda V8.2 has been ported to the latest Ardence ETS real-time operating system (RTOS). This advanced version of ETS, Version 13, offers many new features, including kernel-level memory protection, a critical feature for Aonix's customers who need to bring real-time, secure memory applications into the Windows environment.

Ardence's Phar Lap ETS, a hard real-time RTOS designed for applications targeting execution on x86-based platforms, now boasts improved connectivity support. With this edition, ETS delivers TCP/IP multicast support and complete access to ETS TCP/IP APIs enabling development of network drivers and for support of higher layer protocols. Its 256 priority levels enable developers to meet the needs of real-time applications that are highly complex, guaranteeing that critical thread context switches and yields to threads of higher priority occur in the 500 nanosecond to less than two microsecond range. The ETS kernel-level memory protection safely isolates critical parts of the application from all other parts, ensuring that mission-critical components cannot be compromised.

“Aonix has been an ETS reseller for more than ten years with a great track record of success in supporting complex real-time systems,” stated Stephen M. Woodard, VP, Product Line Executive, Embedded/OEM Division at Ardence, a Citrix company. “We're delighted they continue to deliver the value offered in our real-time solutions, and we look forward to jointly servicing the Ada community with them.”

“The improved interrupt handling support and superior performance of ETS 13 is critical to our customers,” said Gary Cato, Director of Strategic Alliances at Aonix. “Our latest ObjectAda technology complements the improvements made with ETS, giving our customers the solution needed to create hard real-time applications for Intel-target applications.”

The Aonix ObjectAda for Windows brings the improvements of ObjectAda 8.2 to the Windows development platform. In integrating current Windows improvements with the Aonix Ada 95 compiler, Aonix has delivered enhancements to the object code and symbolic debugging information generation and provided full compatibility with the Microsoft Visual Studio .NET 2003 development tools. Recognizing the growing number of large-scale Ada projects, ObjectAda 8.2 for Windows targeting x86 processors offers dramatic performance improvements for developers linking executable files or initiating debugging sessions for large programs.

ObjectAda for Windows targeting Ardence ETS is available immediately and is priced starting at $15,499 (U.S. dollars) per seat with volume discounts available.
