JamaicaVM is a hard realtime Java bytecode-based Virtual Machine, with fully deterministic and preemptable garbage collection. JamaicaVM has been optimized for use in critical embedded platforms. It allows the user to port J2SE - Java Standard Edition - code on virtually any 32&64bit platforms with much improved quality and reliability of application code based on a reduced software development cycle. JamaicaVM support the OpenJDK extensively.


  • Run your Java Code on Embedded with no Change

    Design standard Java code, run it and focus on your application specifics - not on platform specifics

  • Be in Control of the Optimization of your Code

    Delivered set of tools that allows fine tuning of performance of your code onto the embedded machine

  • Move your code on (m)any Hardware

    A large variety of embedded-grade RTOS and processors supported

  • Safe, Secure and Realtime

    Technology is hard-realtime and deterministic by design, making even most stringent safety and security features doable

  • Reduce Cost

    Keep your edge hardware compact and deploy software on resource stringent hardware
