DDC-I Announces DO-178C DAL A Support for NXP’s Layerscape QorIQ LS1043A and LS1048A Processors

Accelerates development, certification and deployment of Layerscape-based DO-178C safety-critical avionics applications

 

Phoenix, AZ – July 31, 2019 – DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced the availability of its Deos™ DO-178C certifiable safety-critical real-time operating system (RTOS) for NXP’s Layerscape QorIQ LS1043A and LS1048A processors, with verification evidence to Design Assurance Level A (DAL A). Layerscape processors running Deos provide a modular, high-performance, reusable platform for quickly developing and certifying avionics applications to DO-178C DAL A, the highest level of safety criticality.

“Deos cache partitioning, memory pools and time/space partitioning allow avionics developers to take full advantage of Layerscape’s high-performance multicore computing and versatile I/O and networking facilities while minimizing worst-case execution time,” said Greg Rose, vice president of marketing and product management at DDC-I. “Avionics designers utilizing Layerscape processors now have a flexible, reusable COTS platform to quickly develop safety-critical avionics applications with an accelerated, low risk path to flight safety certification.”

QorIQ® LS1043A and LS1048A processors are quad-core,  Arm®-based SoC processors that combine four Arm® Cortex®-A53 cores with 32 kbytes of instruction and data cache per core and 1M byte of L2 cache shared among the cores. Featuring integrated security, power management, coherency fabric, and data path acceleration capabilities, plus integrated I/O processing, the processors offer versatile I/O and networking interfaces such as Gigabit Ethernet, IFC and Quad SPI flash, PWM, GPIO, USB 3.0, SATAIII, PCIe, I2C, SPI, and Flex Timers.

Deos is a field proven, safety-critical, avionics RTOS that is used to host a multitude of flight critical functions such as air data computers, air data inertial reference units, cockpit video, displays and flight instrumentation, flight management systems, engine management, and many more.  Built from the ground up for safety-critical applications, Deos is the only certifiable time- and space-partitioned COTS RTOS created using RTCA DO-178, Level A processes from the very first day of its product development. Deos’ unique modular design and verification evidence provides the easiest, lowest cost path to DO-178C DAL A certification, the highest level of safety criticality.

DDC-I’s SafeMC™ technology extends DDC-I’ s advanced time and space partitioning capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class multicore performance without compromising safety-critical task response and guaranteed execution times.
