At a recent Software Defined Radio Forum (SDRF) meeting in Portland, Oregon, PrismTech showcased their Software Communications Architecture (SCA) implementation on a small form factor “motherboard” by Gumstix. The SCA, along with a Common Object Request Broker Architecture (CORBA) middleware layer, is essential for building interoperable radios and waveforms. I caught up with PrismTech’s Steve Jennis, SVP of corporate development, and Gordon Kruberg, CEO of Gumstix, to dig into the significance of this SDR implementation.
