DDC-I, a leading supplier of software and professional services for mission and safety-critical applications, today announced the integration of Real-Time Innovations (RTI) Connext® DDS Micro connectivity framework with DDC-I’s Deos avionics real-time operating system. The integrated platform provides a modular, DDS framework for real-time messaging and information sharing between Deos and FACETM applications.
“We’re excited to be working with RTI to offer avionics developers a certified conformant FACE Transport Services Segment (TSS) platform with DDS connectivity that facilitates seamless, safety-critical communications and data exchange between FACE applications and our DO-178 Deos real-time operating system,” said Greg Rose, vice president of marketing and product management at DDC-I. “The integrated solution combines world-class performance and safety certification capabilities with a proven DDS framework that streamlines communications, accelerates integration, and enhances application portability.”
“Deos is an excellent safety-critical RTOS platform for our connectivity software,” states Chip Downing, senior market development director of aerospace and defense at RTI. “Together, Deos and Connext DDS Micro provide an open architecture solution that combines FACE, POSIX, and DDS into a COTS solution stack that reduces integration and certification risk while accelerating time to market and deployment of critical avionics systems.”
RTI Connext DDS Micro provides a small-footprint modular messaging solution and software connectivity framework for resource-limited devices that facilitates information sharing in real time, enabling applications to work together as an integrated system. Based on the Object Management Group® (OMG®) Data Distribution Service™ (DDS) standard, RTI Connext DDS features peer-to-peer communications, optimized publish/subscribe and real-time Quality of Service (QoS).
RTI Connext DDS Micro is designed to meet the demanding requirements of critical airborne systems requiring low latency, high reliability, scalability, security and COTS DO-178C DAL A certification evidence. RTI Connext TSS is the first certified, conformant FACE™ Transport Services Segment (TSS), enabling rapid interoperability of FACE system components and networked platforms.
Deos is a safety-critical embedded RTOS that employs patented slack scheduling, memory pools and cache partitioning to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS. First certified to DO-178 DAL A in 1998, Deos provides a FACE Safety Base Profile that features 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 multicore performance without compromising safety-critical task response and guaranteed execution time. SafeMC™ employs a bound 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 multicore 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 Multi-Core Processors (MCP), as specified by the Certification Authorities Software Team (CAST) in its Position Paper CAST-32A for Multi-core Processors.
