DDC-I Features Fully Integrated Avionics Display System at Army Aviation Mission Solution Summit

DDC-I has announced that it will exhibit at the Army Aviation Mission Solution Summit. The summit runs from May 14-16 at the Gaylord Opryland Hotel & Convention Center in Nashville, TN.

DDC-I will showcase its Deos safety-critical real-time operating system (RTOS), which utilizes the latest DO-178C Design Assurance Level A (DAL A) multi-core verified baseline. DDC-I will also demonstrate a fully integrated avionics display system featuring Deos.

The demo was created using the Ansys SCADE display design and development environment, which runs on an NXP i.MX8qm processor with an integrated Vivante GC7000 GPU. Utilizing CoreAVI VkCoreGL SC driver and libraries, the demo creates graphical instruments and groups data from multiple systems onto a single display.

“We’re excited to be part of the Army Aviation Mission Solution Summit and look forward to demonstrating our world class, safety-critical RTOS platform and advanced display capabilities to the army aviation community,” said Gary Gilliland, vice president of marketing at DDC-I.

Gilliland continued, “Multicore COTS systems equipped with Deos provide an ideal platform for rapid development, certification and deployment of safety-critical software for a broad range of Army aviation applications requiring advanced display capability.”

The annual Army Aviation Mission Solution Summit, sponsored by the Army Aviation Association of America (AAAA), is an opportunity for the army aviation community to gather in one place at one time to focus on solutions for warfighters. The summit aims to transform aviation warfighting and strengthen trust within the aviation community. Attendees can expect discussions, networking opportunities and updates on aviation technologies and strategies.

Deos is a safety-critical embedded RTOS that employs patented cache partitioning, memory pools and safe scheduling to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS on multi-core processors.

First certified to DO-178 DAL A in 1998, Deos provides FACE Conformant OSS Safety Base and Safety Extended Profiles that feature hard real-time response, time and space partitioning, with support for Rate Monotonic, ARINC-653 and POSIX interfaces.

SafeMC technology extends Deos’ capabilities to multiple cores, enabling developers of safety-critical systems to achieve multi-core performance without compromising safety, critical task response and guaranteed execution time.

SafeMC employs a bounded multiprocessing (BMP) extension of the symmetric multiprocessing architecture (SMP), safe scheduling and cache partitioning to minimize cross-core contention and interference patterns that affect the performance, safety criticality and certifiability of multi-core systems. These features enable avionics systems developers to address issues specified by AC/AMC 20-193 multi-core objectives that could impact the safety, performance and integrity of a software airborne system.
