PrismTech Corp. in Burlington, Mass., and Green Hills Software in Santa Barbara, Calif., announced a small, fast operating environment for software-defined radio (SDR). The environment, which complies with the Software Communications Architecture (SCA), features PrismTech’s Spectra OE operating environment running on the Green Hills Integrity real-time operating system. Spectra OE is SCA v2.2.2-compliant and includes a core framework, embedded ORB middleware, XML parser, and CORBA object services in a consolidated footprint of less than 2 megabytes. Green Hills Software’s Integrity is certified to the IEEE POSIX.1-2003 specification. To date, Integrity has been used on several SDR programs that depend on the SCA v2.2 and v2.2.2 interface. Designed for security, reliability, and performance, Integrity provides the foundation for SDR platform development. The operating system provides CPU time, memory, and file system resource guarantees for critical radio applications and SDR waveforms. Its partitioning ensures that applications and waveforms always have the resources necessary to run and cannot corrupt other applications or waveforms that are executing. Integrity’s virtual device driver support provides added security and re-configurability required in SDR devices. PrismTech’s Spectra SDR Developer Suite is integrated with the Spectra OE running on Integrity to provide an integrated suite of SCA waveform modeling, code generation, test, and deployment development tools.
