DDC-I’s Rose: Deos is first commercial RTOS supporting ARINC 653 Part 4 strict subset

PHOENIX, 5 April 2012. “The availability of verification evidence and proven certifiability are key for [the avionics] market,” says Greg Rose, vice president of marketing and product management at DDC-I in Phoenix. DDC-I staff and solutions, including its Deos real-time operating system (RTOS), are laser focused at serving the DO-178 safety-critical avionics market, he says.  

“We are the first ones to come up with a product just supporting the strict subset of ARINC 653 Part 4, targeted at the majority of avionics on the airplane—the line replaceable units (LRUs),” Rose explains. “ARINC 653 standardized the operating system interface for avionics, and that was mainly targeted at integrated modular avionics (IMA) systems. Part 4 is targeted at all the other devices and basically allows them to leverage standards conformance. They simplified the programming model and the tasks such that it is scalable for less-complex systems.

“We have all the building blocks for a data monitoring, recording, and presentation device available off the shelf,” Rose adds. “Deos is a powerful platform for avionics development and cutting the cost of certifications for our customers. DDC-I offers customers the ability to reuse certification artifacts. The ability to not have to recertify every time is key; and, the ability to import external software that is written to ARINC 653 Part 4 just gives users one more arrow in their quiver.”
