Oct. 21, 2021 - McObject and Lynx Software Technologies announce the release of eXtremeDB/rt, the first and only commercial off-the-shelf (COTS) real-time database management system for embedded systems that works together with the RTOS to ensure that tasks complete within their CPU budgets and transaction deadlines. A crucial distinction of a hard real-time system is it must complete tasks within the assigned CPU budget.
But a conventional database system’s transaction has no time constraint, so a database transaction could commit but cause the task to exceed the CPU budget and be interrupted, causing the real-time system and the database to be incoherent. eXtremeDB/rt maintains the external and internal consistency of data by introducing time-cognizant transaction managers to eliminate this “impedance mismatch.” LynxOS-178 is a native POSIX, hard real-time partitioning operating system developed and certified to FAA DO-178B/C DAL A safety standards.
It is the only COTS OS to be awarded a Reusable Software Component (RSC) certificate from the FAA for re-usability in DO-178B/C certification projects and has been deployed in millions of safety-critical applications worldwide, including multiple military and aerospace systems. “We were delighted to work with McObject to bring eXtremeDB/rt to the LynxOS partner ecosystem. Our companies share the vision that real-time systems are becoming more sophisticated and consequently have to manage more complex data. eXtremeDB/rt fills a critical gap in the technology stack,” said Pavan Singh, vice president of product management, Lynx Software Technologies.
The combination of LynxOS and eXtremeDB/rt will be of interest to developers of real-time avionics, navigation, autonomous systems, railway systems as well as nuclear and energy systems. Andrei Gorine, CTO of McObject, says “ Lynx has led the market for years in providing LynxOS as a powerful, safety-critical RTOS. The depth and breadth of applications in the market that require hard real-time capabilities is growing every day. It’s clear that using our technologies together will provide a competitive solution for developers of mission- and safety-critical systems.”
