DDC-I and OpenSystems Media Announce Tech Cast for ARINC 653, Part 4 Interface

Targeting Avionics LRUs

Phoenix, AZ. July 19, 2012. DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it is offering an on-demand Tech Cast focusing on the Part 4 Subset of the ARINC 653 application/executive interface for avionics Line Replaceable Units (LRUs). Hosted by Open Systems Media, the complementary Tech Cast targets engineers, programmers, and managers interested in the latest developments in operating systems for avionics and other safety-critical applications.

The Tech Cast begins with an overview of ARINC 653 Part 1. It then focuses on the Part 4 subset and its application as a lightweight alternative to Part 1 for embedded, real time operating systems used in avionics LRUs. The TechCast is available at http://bit.ly/ARINC_TechCast.

ARINC Specification 653 defines an application/executive interface between an avionics computer’s operating system and application software that simplifies software design, enhances portability and reuse, and reduces the cost of avionics software certification. The Part 4 subset, which uses a compatible but simplified execution model, is defined for systems that do not require the size, complexity and features of the full specification.

Deos is the first DO-178B Level A certifiable embedded RTOS to provide support for the ARINC Specification 653, Part 4 strict subset. Deos 653p4-Solo™ provides the ARINC Specification 653 Part 4 services at a very high value point. DDC-I also offers an enhanced hybrid solution that provides all the value-added features of Deos (rate monotonic slack scheduling, interrupt driven response, binary reuse, IO middleware, etc.) in addition to support for the Part 4 services and scheduling model.

Deos has been used in hundreds of safety critical avionics applications on commercial and military aircraft. 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.
