JamaicaVM is a hard realtime JVM and object oriented software development environment, including analysis tools which can:

Increase your productivity
Improve application reliability
Provide a safe execution environment
Simplify code reuse and encapsulation

JamaicaVM achieves these advantages through a unique clean room implementation of Java virtual machine technology optimized for time critical, safety critical, and embedded systems. JamaicaVM provides:

Hard realtime guarantees
A Real Time Specification for Java implementation
Efficient ahead-of-time static compilation
Fast execution time
Smart Linking for low memory footprint

If you thought that the execution speed and garbage collection of Java was incompatible with realtime performance, it is time for you to try JamaicaVM.

FEAUTURES & BENEFITS

Hard Realtime Execution
JamaicaVM provides hard realtime guarantees for all primitive Java operations. This enables all of features of Java to be used for your hard realtime tasks – features essential to object-oriented software development such as dynamic allocation of objects, inheritance, and dynamic binding now become available to the realtime developer.
Realtime Garbage Collection
JamaicaVM provides the only Java implementation with a highly efficient hard realtime garbage collector. The garbage collector runs in small increments of only a few machine instructions but still guarantees to recycle all reclaimable memory, avoiding memory fragmentation, all while providing bounded execution time for all allocations.

Fast & Small
JamaicaVM’s optimizing static compiler ensures excellent runtime performance. Its profiling tool gathers information for ensuring optimization of both runtime performance and code size. Sophisticated automatic class file compaction, smart linking for dead code elimination, and partial compilation techniques ensure minimal code footprint.
Dynamic Loading of Code
The full power of Java becomes available through the use of dynamic class loading. This enables the program updating, the addition of new features and functionality, and easy end-user customization.
Powerful Tools JamaicaVM is Eclipse IDE compatible. Tools for program analysis, thread monitoring, static compilation, and creating ROM-able code are highly integrated and easy to use.
