Accelerated Technology's Nucleus POSIX Complies with Software Communication Architecture to Aid Developers of Military and Aviation Applications

MOBILE, Ala., Feb. 23, 2005 -Accelerated Technology{reg}, a Mentor Graphics division (Nasdaq: MENT), today announced a new version of the Nucleus{reg} POSIX kernel that is compliant with the Software Communication Architecture (SCA) version 3.0, a set of standards for deploying and interconnecting the signal processing objects of a software defined radio (SDR) system. The Nucleus POSIX SCA kernel now provides developers of military and aviation communication devices with benefits that include software reusability, system scalability and interoperability and rapid insertion of new technologies into fielded SDR systems.

SCA is a key technology for developing versatile, interoperable SDR systems. The U.S. Department of Defense's Joint Tactical Radio Systems (JTRS) Joint Program provides a family of software programmable radios such as handheld, vehicular, base station (fixed and maritime), airborne and dismounted radios-all designed around the SCA for different military domains.

Developers using the Nucleus POSIX SCA kernel, in conjunction with software such as Common Object Request Broker Architecture (CORBA), CORBA services and the CORBA component model, can reprogram an SDR system so that a single piece of hardware can be configured to meet the needs of situations that include the modern battlefield. For example, a single unit will be able to send or receive multiple different waveforms (or forms of modulation), and operate in different frequency bands, so that it can communicate with virtually any current software radio or legacy (pre-existing) system, and operate with the lowest possibility of detection or interception by unauthorized or unfriendly listeners. In addition to the robust Nucleus POSIX SCA kernel, developers can build their SDR systems quickly using associated middleware including support for memory management unit (MMU), dynamic download (DDL), InterProcess Communication (IPC) and file management software.

"SDR systems are expected to improve the ability to communicate in modern battlefields as well as in other areas where communication abilities can be limited. The new Nucleus POSIX SCA kernel can help embedded system developers meet these needs by offering them flexibility, reliability and high performance to build military communication devices," said Robert Day, director of marketing, Mentor Graphics Embedded Systems Division.

Availability and Pricing

The Nucleus embedded software is licensed with source code and without royalty fees. Available now as an add-on component to the Nucleus PLUS kernel, licenses for the Nucleus POSIX SCA software start at U.S. $2,995. For more information, please contact Accelerated Technology at 800-468-6853.
