Boston, MA— Aonix released its Perc 4.1 platform on Sept. 15 at the Embedded Systems Conference (ESC) Boston 2003. Perc 4.1 is a Java virtual machine designed to provide real-time control for mission-critical network infrastructure, military command and control, industrial automation, and commercial telematics. Consequently, Perc 4.1 provides a pacing agent and profiling tools that enable developers to achieve accurate real-time control of their applications.

Royalty-free project licensing packages of Perc 4.1 will begin shipping in October 2003. Aonix (San Diego, CA; Paris, France) delivers complete solutions for safety- and mission-critical applications.

The company says that successful real-time control is critical to developers' ability to manage their application's memory. In most real-time designs, determining the correct combination of parameters requires experimentation, and many applications require different pacing parameters for each phase of execution, combinations of concurrently executing application components, and varied hardware configurations.

Using a new garbage-collection pacing API, Perc 4.1 pacing agent monitors memory allocation behavior of the application workload and automatically adjusts the timing and ratios of CPU-time increments dedicated to garbage collection activities. Source code for the pacing agent is provided for developers, who need to fine-tune it for specialized system needs. The pacing agent ensures that no garbage collection increments are scheduled for times already set aside for execution of application tasks in the real-time workload. This allows the pacing agent to simplify development, and improves the system's responsiveness to workload changes.

'This release builds on longstanding Perc traditions,' says Kelvin Nilsen, Aonix’s CTO and Perc’s founder. 'Aonix is focused on providing multilanguage support to the development of mission-critical systems. As its Java offering, Perc offers standard J2SE libraries and development tools with sub-millisecond timing precision and high reliability thanks to its advanced memory management and enhanced high-precision timing services.'

In addition, using Optimizeit 5.0 Perc Edition, developers can pinpoint and resolve performance bottlenecks. Developed and distributed by Borland for desktop and server applications, Optimizeit is recognized as the best optimization and profiling tool available for Java, according to Aonix. To make Optimizeit work even better with embedded targets, Aonix has implemented a Perc-specific reduced-memory embedded agent for Optimizeit. This embedded agent reduces Optimizeit memory requirements on the embedded target to a much smaller target footprint than the Optimizeit enterprise and desktop products require.

Workinge benchmarks. New platform support includes WindRiver's Tornado 2.2 development environment; support for RedHat 8.0 and 9.0; and integration of the Perc Shell and Perc Target Server tools with Eclipse IDE. Aonix has also added many JDK 1.4-compliant Java libraries such as java.util.logging and java.util.prefs packages as well as updating collections classes and JDBC 3.0 support to the existing JDK 1.3-compatible product.
