McObject Announces the Release of eXtremeDB/rt 1.2

eXtremeDB/rt 1.2 advances first-of-its-kind hard real-time DBMS

May 18, 2023, Seattle: McObject® announces eXtremeDB®/rt 1.2, the latest release of its seminal embedded database management system for hard real-time systems. 

Among the new features found in eXtremeDB/rt 1.2 are:

  • Support for Asymmetric MultiProcessing (AMP) architecture systems. These systems are characterized by having two CPUs of differing architecture, typically executing different operating systems (e.g., INTEGRITY® and Linux), and a large amount of memory shared by the CPUs that can be used for an in-memory database available to both CPUs.
  • Hard real-time performance counters and a micro-web server with a REST API used to attach a GUI dashboard to visualize the counters.
  • Online backup
  • Support for the latest RTOS releases including Nucleus™, Azure RTOS (ThreadX), VxWorks®, MICROSAR, INTEGRITY and others. The full list of supported platforms can be found at

Notable among the new platforms supported is the NXP® i.MX 8 QuadMax and QuadPlus MCUs, combining Cortex M cores for real-time tasks and Cortex A for low-latency multi-processing. These MCUs feature the ability to run different operating systems (e.g., FreeRTOS™ on the M core and Linux on the A cores), with memory shared between the sides. eXtremeDB/rt support for these platforms includes a unique custom synchronization implementation so that an in-memory database can be shared between the sides. Steven Graves, CEO of McObject, says “We are excited to announce the release of eXtremeDB/rt version 1.2. This new release includes several important new features that make eXtremeDB/rt an even better choice for real-time systems. With its support more target platforms and RTOS, the range of real-time systems that can benefit from eXtremeDB/rt has been greatly expanded. eXtremeDB/rt is the most powerful and reliable embedded database system available, and the only one offering support for hard real-time transactions.”
