PHOENIX, Ariz., 20 April 2016.DDC-I, a supplier of software and professional services for mission- and safety-critical applications in Phoenix, is introducing a reduced-footprint implementation of its safety-critical, DO-178C-certifiable Deos real-time operating system (RTOS). The new small-footprint RTOS targets ultra-reliable microcontrollers (MCUs), which are optimized for safety-critical applications, including commercial and general aircraft avionics, from NXP Semiconductors N.V., a global semiconductor manufacturer headquartered in Eindhoven, The Netherlands.
The NXP MPC56XX and MPC57XX families of processors, built on Power Architecture technology, feature hardware and software compatibility across the product line. Available in single- and dual-core versions with scalable processor speeds from 32 MHz to over 300 MHz, the processors provide a versatile, scalable mix of onboard memory, peripherals, and thermal qualities that make it very attractive for avionics end-point applications operating in the harshest environments requiring the utmost in safety, reliability, and software integrity, officials say.
DDC-I’s Deos supports these devices with a time- and space-partitioned RTOS that is certifiable to DO-178C Design Assurance Level (DAL) A, enabling avionics applications with mixed criticality to be integrated safely on the same processor in the same operating environment. Developers now have the ability to run high design assurance flight-critical applications on the same processor as lower-criticality maintenance and monitoring functions in flight, maximizing the value-added features they can offer customers on avionics end-point devices.
Deos also includes technology that enables unmodified reuse of not only software, but also its related certification artifacts. User applications can be bundled as separately loadable binary modules. This modularity allows users to integrate software easily and reuse its associated verification evidence between products and programs, thereby achieving significant cost and schedule savings.
Deos’ binary modularity also facilitates software development and integration between multiple application groups or third-parties, enabling developers to independently develop binaries and easily integrate them into the avionics device.
“The NXP MPC 56XX and 57XX families of processors are ultra-reliable MCUs offering best in class quality, reliability and safety for the harshest environments,” says Greg Rose, vice president of marketing and product management at DDC-I. “Deos’ time and space partitioning gives avionics developers a multitude of options for integrating advanced features into end point control devices not previously available to them when leveraging these powerful microcontrollers.”
“Deos’ partitioning coupled with its unique binary modularity gives application developers the ability to easily snap together and qualify systems built with applications from multiple parties,” Rose adds. “It also reduces recertification time, which makes it easier to enhance current products with new features.”
Deos is a safety-critical embedded RTOS that has been certified to DO-178 DAL A since 1998. Featuring deterministic real-time response, the time and space partitioned RTOS employs patented 'slack scheduling' and cache partitioning to deliver faster worst-case response and higher CPU utilization than any other certifiable safety-critical COTS RTOS.
Deos was built from the ground up for safety-critical applications, and is the only certifiable time- and space-partitioned COTS RTOS that has been created using RTCA DO-178, Level A processes from the very first day of its product development, according to company officials. Deos provides an easy, low-cost path of any COTS RTOS to DO-178 Level A certification, the highest level of safety criticality.
