New PERC Release Extends Leadership among Real-Time Virtual Machines
Apr 04, 2006 - 18:43 PM
PERC Ultra introduces full Java™ 5 language features such as generics, annotations, and type-safe enumerations. Along with these language revisions, PERC Ultra also includes enhancements of key packages from the Java™ Standard Edition library set to take advantage of Java™ 5 features, as well as new libraries such as java.util.concurrent and java.nio.channels.
In addition to Java™ 5 capabilities, PERC Ultra also introduces a variety of performance, porting, and tool improvements. Tool enhancements for PERC Ultra include integration with the Eclipse TPTP profiling capability, shell enhancements, easier installation, and improved help. New ports include WinCE/XScale, VxWorks 6.x for PowerPC, Linux XScale Big Endian, and support for the latest safety-critical version of LynxOS. Performance enhancements include optimized reclamation of large objects, a 12% footprint reduction due to optimized C stack space, and a 7% reduction in memory requirements for zip and jar files.
“Key to the success of PERC has been the Aonix commitment to focus on Standard Edition compatibility,” said Kelvin Nilsen, Aonix CTO. “With PERC Ultra, developers are able to take advantage of the Java™ 5 Standard Edition functionalities that save tremendous development time, cut development costs, and ensure portability between platforms. With PERC Ultra, the developer gains the advantages of Java with an embedded Java footprint.”
“Aonix is committed to keeping developers up-to-date with current SE libraries,” noted Dave Wood, Aonix director of product marketing. “With this release, PERC Ultra will be as much as three Java™ versions ahead of our nearest competition in the embedded space. Aonix has earned a reputation as the leader in compatibility and responsive support, and we take that legacy very seriously.”
PERC Ultra, a major upgrade from previous version PERC 4.2, reflects an important evolution of PERC from a single product to a growing family of products that covers a broader range of embedded applications needs than any competing Java™ solution. PERC Ultra and PERC Pico are the products in the expanding PERC product line. PERC Ultra is the ideal solution for embedded applications of high complexity, thanks to PERC Ultra’s predictable performance and its extensive support of off-the-shelf J2SE libraries and components.
Its sister product, PERC Pico, meets the needs of resource-constrained hard real-time applications, featuring performance and footprint characteristics comparable to C. Not only is PERC Pico smaller and faster than any other real-time virtual machine, it even offers low-level device access and interrupt handling and preserves key virtues of Java™ such as portability, reliability, and scalability.
PERC Ultra and PERC Pico are interoperable within a single application. For the first time, it is now possible for Java developers to create complete complex applications from infrastructure to the device level, without resorting to the use of other languages with less portability and robust memory use for specialized components.
