Higher Availability and Lower Costs

JamaicaVM reduces the time spent developing and managing embedded systems that run with higher availability and reduced lifecycle costs.

Architectural Flexibility

Run critical and third party applications uninterrupted and fully protected against intrusions.

Easier Programming

Have control of your code with significantly easier programming in Java.

Application Priority

Develop and run code with a focus on application specifics – not platform limitations.

Less Effort

Significantly improve application quality and reliability with resources that reduce your software development cycles.

Technical Highlights

Real time specification supported by automatic memory deallocation, object-oriented programming.
  • Deterministic Garbage Collection

    Built-in deterministic garbage collection replaces the threat of execution interruptions with the reliability of deterministic realtime Java bytecode and full hardware abstraction.

  • RTSJ Support

    JamaicaVM supports hard realtime down to >10µs based on native support of the Real-Time Specification for Java (RTSJ) for assurance that systems will perform as expected.

  • Tools / Standard Libraries

    JamaicaVM comes with tools that enable you to quickly develop your application. This includes complete cross-compilation tools including trace analysis and emulation. Support of OpenJDK libraries and Java Standard Edition compliance.
