Green Hills Software and AICAS announce integrity RTOS integration with the JamaicaVM.Green Hills Software, Inc. announced recently the availability of aicas' JamaicaVM realtime Java Virtual Machine A Java interpreter. The Java Virtual Machine (JVM) is software that converts the Java intermediate language (bytecode) into machine language and executes it. The original JVM came from the JavaSoft division of Sun. (JVM See Java Virtual Machine. JVM - Java Virtual Machine ) for Green Hills Software's INTEGRITY RTOS (1) (RealTime Operating System) An operating system designed for use in a real time computer system. See real time system, embedded system, process control and OS-9. . 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 (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of aicas. "Our Java software provides Green Hills Software end users increased productivity, high reliability, safe execution, and easy code reuse and encapsulation (1) In object technology, the creation of self-contained modules that contain both the data and the processing. See object-oriented programming. (2) The transmission of one network protocol within another. ." 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 worst-case execution time (WCET) of a computational task is the maximum length of time the task could take to execute on a specific hardware platform. Knowing worst-case execution times is of prime importance for the timing analysis of hard real-time systems. . 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. JamaicaVM for the INTEGRITY RTOS on PowerPC and Blackfin processors is available today from aicas. Founded in 1982, Green Hills Software, Inc. is the technology leader for realtime operating systems and software development tools for 32- and 64-bit embedded systems. Our royalty-free INTEGRITY RTOS, velOSity microkernel (1) The part of an operating system that is specialized for the hardware it is running in. The other components of the OS interact with the microkernel in a message-based relationship and do not have to be rewritten when the OS is ported to a new platform. , compilers, MULTI MULTI Multiple and AdaMULTI Integrated Development Environments and TimeMachine debugger offer a complete development solution that addresses both deeply embedded and high-reliability applications. Green Hills Software is headquartered in Santa Barbara, CA, with European headquarters in the United Kingdom. |
