Spectrum flexComm SDR-4000 Software Defined Radio Subsystem
Now Integrated with Objective Interface Systems ORBexpress RT

Partnership delivers small-footprint Common Object Request Broker Architecture (CORBA) on small
form factor software defined radio platform

Burnaby, B.C., Canada and Herndon, VA—June 20, 2006 — Spectrum Signal Processing Inc. and Objective Interface Systems, Inc. today announced they have entered into an agreement to integrate and market Objective Interface’s ORBexpress^® RT with Spectrum’s flexComm™ SDR-4000 software defined radio (SDR) signal processing platform.

ORBexpress RT is a real-time CORBA Object Request Broker (ORB) that enables software developers to simplify the development of distributed software applications, build scalable, efficient and robust applications, and reduce overall development time, meeting time-to-market requirements. The SDR-4000 is Spectrum’s new, ruggedized commercial-off-the-shelf software defined radio platform that supports the Software Communications Architecture (SCA).

“ORBexpress RT is fast, lean and predictable, making it ideal for use with the SDR-4000 to support digitization and processing of complex waveforms requiring low-latency deterministic operation,” said Mark Briggs, Vice President, Marketing at Spectrum Signal Processing. “Furthermore, ORBexpress is free of a run-time license, thereby minimizing its cost when used in volume deployments. The size, weight, power and performance attributes of the SDR-4000 integrated with ORBexpress make it ideally suited for volume mobile radio applications.”

“By integrating one of the most widely adopted ORBs in the defense and military space with an industry-leading signal processing platform, Objective Interface and Spectrum can provide integrated software defined radio solutions that simplify our customers’ supply chains,” said Joseph Jacob, Senior Vice President, Sales and Marketing at Objective Interface Systems. “Our solution can reduce our customers’ time-to-deployment and mitigate the time, risk and expense of in-house development.”

The SCA, developed by the United States Department of Defense for its Joint Tactical Radio System program, specifies how hardware and software elements of a radio interact to support software defined radio functionality. A key component of the SCA is the requirement to use CORBA as a middleware layer for the application framework and waveform application components operating on general-purpose processors. ORBexpress RT provides critical real-time CORBA capabilities to support deterministic systems where speed, predictability and reliability are important. It provides a minimal footprint, low latency and low overhead to allow software defined radio developers to build scalable, efficient and robust applications.

Spectrum’s SDR-4000 3U CompactPCI^®-based rugged platform uses heterogeneous processing to provide high-performance, real-time signal processing for tactical military radios. The platform includes the PRO-4600 software defined radio modem processing engine and the XMC-3321 dual-transceiver input/output mezzanine card. The SDR-4000 also includes Spectrum’s quicComm™ hardware abstraction layer and software development library.

Details on the SDR-4000 can be found at www.spectrumsignal.com/products.
