Software-Defined-Radio Operating Environment Is Small, Fast

PrismTech’s Spectra Operating Environment (OE) and Green Hills Software’s Integrity real-time operating system (RTOS) have been integrated to create what the two companies are calling the smallest and fastest complete Software Communications Architecture (SCA)-compliant software-defined radio (SDR) operating environment. Spectra OE complies with SCA v2.2.2 and includes a core framework, high-performance embedded ORB (Object Request Broker) middleware, XML (eXtended Markup Language) parser, and CORBA (Common Object Request Broker Architecture) object services in a consolidated footprint of less than 2 Mbytes. PrismTech’s Spectra SDR Developer Suite is also fully integrated with the Spectra OE running on Integrity to provide a seamlessly integrated suite of SCA waveform modeling, code generation, test, and deployment development tools.

Green Hills’ royalty-free Integrity is certified to conform with the latest IEEE POSIX.1-2003 specification, which is key to supporting both the SCA v2.2 and v2.2.2 API. Integrity provides CPU time, memory, and file system resource guarantees for critical radio applications and SDR waveforms. Its brick-wall partitioning ensures that applications and waveforms always have the resources needed to run and cannot corrupt other applications and waveforms that are executing. The RTOS’s virtual device driver support provides the added security and reconfigurability needed in SDR systems.
