Green Hills Software and aicas Announce INTEGRITY RTOS Integration with the JamaicaVM

Embedded and Realtime Java Users Benefit from Increased Productivity, High Reliability, and Safe Execution



SANTA BARBARA, CA, March 8, 2005—Green Hills Software, Inc., the technology leader in embedded software development tools and royalty-free realtime operating systems, and aicas, provider of Java technology for realtime and safety critical embedded applications, announced today the availability of aicas' JamaicaVM realtime Java Virtual Machine (JVM) for Green Hills Software’s INTEGRITY RTOS. The JamaicaVM supports INTEGRITY native threads and inter-process communication, and offers a runtime system for hard realtime applications through the use of the JamaicaVM's realtime garbage collection technology. The JamaicaVM is the only available Java implementation that provides hard realtime support for the full Java language.

Because the INTEGRITY RTOS features full memory protection and guaranteed resource availability for application protection, the INTEGRITY port to the JamaicaVM provides substantial portability, developer productivity, and flexibility for safety-critical and realtime software applications.

“JamaicaVM support for INTEGRITY represents a significant step in the evolution of embedded development. Developers can now expand their portfolio to include embedded Java technology,” said Dr. James Hunt, CEO of aicas. “Our Java software provides Green Hills Software end users increased productivity, high reliability, safe execution, and easy code reuse and encapsulation.”

The advanced memory management of the JamaicaVM makes garbage collection activity completely predictable, so that even high priority threads can perform hard realtime tasks without interruptions. Dynamic allocation can be performed with a constant worst-case execution time. The garbage collector automatically ensures that memory is quickly recycled and memory loss due to fragmentation is prevented. No user adjustment of garbage collector parameters is required.

An advanced tools suite provides precise control over the deployment configuration of Java applications. The build system includes tools to help determine execution times of allocation operations. Several key features are available with JamaicaVM 2.6:

  • full support of the realtime specification for Java (RTSJ),
  • incremental compilation for significantly reducing development turnaround times,
  • and extended support for Java 1.4 API

Availability

JamaicaVM for the INTEGRITY RTOS on PowerPC and Blackfin processors is available today from aicas.
