DO -178B DDS
Posted October 31st, 2012 by Toc Reporter
October 31, 2012 - Twin Oaks Computing is proud to announce the launch of our new product: CoreDX DDS Safety-critical Edition (CoreDX DDS-SE), unveiled at the Interoperable Open Architecture conference in London earlier this week.
CoreDX DDS-SE has been successfully ported to Green Hills Software’s safety certified INTEGRITY-178B Time-Variant Unified Multi-Processing (tuMP), becoming the first and only communications middleware to be successfully ported to a safety-critical multicore operating system. The integrated CoreDX DDS-SE and INTEGRITY-178B tuMP solution is
targeted at developers of both commercial and military critical systems with high assurance software requirements.
“CoreDX DDS-SE’s analyzable source code and small memory footprint makes it the ideal safety critical DDS solution for our INTEGRITY-178B RTOS product line” said Pat Rodenbeck, Vice-President of Safety and Security Critical products at Green Hills Software. “We have investigated the DDS supplier base for several years, searching for the right DDS solution to integrate with INTEGRITY-178B. After careful review of multiple DDS suppliers we are excited to announce our new partnership with Twin Oaks Computing. Green Hills Software looks forward to the benefits the CoreDX DDS product line will provide our customers.”
Green Hills Software’s INTEGRITY-178B Time-Variant Unified Multi-Processing (tuMP) multicore operating system builds upon a proven eleven year service history and certification pedigree in the safety critical (DO-178B Level A compliant) and security critical (Common Criteria EAL6+ compliant) software market by incorporating patent-pending multicore operating system capabilities, including support for AMP and SMP. These tuMP capabilities enable multiple independent safety and/or security critical applications to execute on a multicore operating environment in a predictable, bounded, and application independent manner.
INTEGRITY-178B tuMP’s partitioning enforcing scheduling method results in a single OS (i.e. unified) that provides practical time-variant scheduling of both AMP and SMP applicationssimultaneously by enabling the association of cores and applications into groupings (called Affinity Groups) corresponding to an end-user intended function (or functions). Sets of affinity groups are then scheduled independently of other sets of affinity groups, permitting time-lines that correspond to application requirements, yet also permitting other sets of affinity groups to be developed that can make use of any of the time windows where cores are not being utilized.
CoreDX DDS-SE is packed with ways to lower risk and save you money:
• CoreDX DDS-SE is designed to be easily certifiable
• CoreDX DDS-SE is standards compliant
• CoreDX DDS-SE has minimal operating system services requirements
• CoreDX DDS-SE has controlled run time memory utilization
• CoreDX DDS-SE has no recursion
• CoreDX DDS-SE has bounded resource utilization
• CoreDX DDS-SE offers a non-threaded implementation
• CoreDX DDS-SE has support for low power CPUs
• CoreDX DDS-SE is completely decentralized and easy-to embed architecture with no message brokers or daemon processes
• CoreDX DDS-SE is scalable
• CoreDX DDS-SE is easily portable to a broad range of platforms
