DDC-I announces ARINC-664 avionics network support for Deos certifiable real-time operating system

DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced the availability of ARINC-664 compliant driver and application support for the Deos™ safety-critical real-time operating system. The ARINC-664 driver complements DDC-I's existing AFDX solution, enabling Deos application programs to now communicate to avionics systems in airframes equipped with either variant of the powerful communications interface, including those from Boeing, Airbus, and a number of other airframe manufacturers.

AFDX (Avionics Full-Duplex Switched Ethernet) is a next-generation, aircraft data network developed for real-time fly-by-wire systems that implement the deterministic Ethernet interface standardized by ARINC Specification 664. These interfaces utilize a cascaded star topology that has the benefits of significantly reduced wire runs and thus enabling lower aircraft weight. The dual-redundant network also enhances reliability and provides guaranteed bandwidth, thereby delivering a high Quality of Service (QoS). DDC-I's library, device driver process, and interfaces enable application developers to have the ability to initialize, configure, and read/write data to any avionic system equipped with an AFDX or ARINC 664 network interface.

"Deos was first certified to DO-178B Design Assurance Level A in 1998," said Bob Morris, president and CEO of DDC-I. "Our continued commitment to support the popular avionics standards, such as our existing AFDX and the new ARINC 664 compliant solution, make it easier than ever for designers of next-generation avionics systems to take advantage of Deos, the industry's most advanced safety-critical RTOS."

Deos has been used in hundreds of safety critical avionics applications on commercial and military aircraft. The time and space partitioned RTOS features deterministic real-time response and employs patented "slack scheduling" to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS. Built from the ground up for safety-critical applications, Deos is the only certifiable time and space partitioned COTS RTOS that has been created using RTCA DO-178B, Level A processes from the very first day of its product development. It also provides the easiest, lowest cost path of any COTS RTOS to DO-178B Level A certification, the highest level of safety criticality.
