Aonix has announced the release of a new version of its Java virtual machine (JVM) for real-time and embedded applications, delivering productivity gains of 2X to 10X and a run-time efficiency comparable to that of C++ implementations, according to the company. Called PERC, the JVM is a “clean-room virtual machine expressly created to manage the complexity of large, dynamic real-time systems,” and it runs under Linux, Windows, and Solaris for deployment on targets running embedded Linux, VxWorks, OSE, or QNX.

Aonix says that Verison 4.2 of PERC delivers a 10 to 20 percent improvement over PERC 4.1 on most benchmarks and up to a 50 percent improvement on string and array-intensive benchmarks. By improving its class loading technology, Aonix has boosted PERC's performance on representative benchmarks by up to 30 percent. Such performance improvements, the company said, are critical for “intelligent, connected systems” such as network infrastructure, vehicle telematics, command and control, and process automation, where Java is catching on.

PERC 4.2 also contains library enhancements particularly targeted at emerging Java markets. These include support asynchronous I/O, JDK 1.4 compatible libraries for non-graphical applications, and the GNU Classpath implementation of AWT graphics libraries, providing a complement to the Eclipse SWT graphical library support that's already a part of PERC.

Operating system support has also been enhanced to ensure that PERC “is kept current with the latest releases and technologies from key RTOS suppliers.” In particular, PERC 4.2 supports MontaVista Linux 3.1, LynxOS 4.0, LynxOS-178 2.0, and QNX 6.2.1 and 6.3.
