DDC-I Joins Multi-core Avionics Webinar as Guest Speaker

Will focus on RTOS memory partitioning and scheduling techniques for boosting AMC20-193 multi-core performance and determinism

Phoenix, AZ – February 13, 2025. DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it will join Aerospace Innovations complimentary multi-core avionics webinar as a guest speaker on Wednesday, February 26 at 10:00 AM EST. Gary Gilliland, Vice President of Marketing at DDC-I, will speak on behalf of DDC-I and focus on Real-Time Operating System (RTOS) techniques for increasing multi-core performance and determinism for safety-critical avionics applications per FAA and EASA A(M)C20-193 multi-core guidelines.

The complexity introduced by multi-core and multi-system architectures, which often incorporate diverse elements such as Systems on Chip (SoC) and blend Multi-Core Processors (MCP) with Open Systems Architecture, presents significant testing challenges for avionics systems. Understanding the behavior of these systems and establishing thorough testing protocols can be difficult. Traditional testing approaches, tailored for single-core environments, fall short in ensuring the accuracy and performance of multi-core systems. Challenges are compounded by issues like data control coupling, safety-critical timing analysis for multi-core setups, the need for deterministic behavior, and the demand for extensive coverage testing.

The latest guidelines under A(M)C20-193, which have superseded CAST-32A, address these complexities. To effectively test and verify these systems, it’s crucial to have a deep understanding of both the hardware and software components involved. This webinar will look at the latest in multi-core systems and challenges, the impact AI can have on their testing and the future of multi-core in modular avionics displays.

“This webinar is a must see for avionics developers who want to utilize the latest multi-core technology while meeting the worst-case execution requirements defined in the A(M)C20-193 guidelines,” said Gary Gilliland, Vice President of Marketing at DDC-I. “We look forward to highlighting A(M)C20-193 compliant memory configuration and scheduling techniques at the RTOS level that minimize cache thrashing and shared resource conflicts, thereby delivering superior multi-core performance and determinism for safety-critical applications.”

About Deos

Deos™ is a safety-critical real-time operating system. First certified to DO-178 DAL A in 1998, Deos combines DO-178C Design Assurance Level A (DAL-A) artifacts with FACE® Technical Standard support that encompasses the Safety Base and Safety Extended Profiles for the Operating System Segment (OSS). The Safety Profiles feature hard real-time response, time, and space partitioning, and both ARINC-653 and POSIX interfaces.

SafeMC™ technology extends Deos’ advanced capabilities to multiple cores, enabling developers of safety-critical systems to achieve best in class 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 that could impact the safety, performance and integrity of a software airborne system executing on MCP, as specified by the FAA and EASA in A(M)C 20-193.
