Take on CORBA for multiprocessor SDR

Posted: 16 Aug 2007 ?? ?Print Version ?Bookmark and Share

Keywords:CORBA for multiprocessor SDR? SCA-based SDR? communications framework?

The trend toward increasingly smaller and higher-performance SDRs means that radio designers must carefully select their component technologyboth hardware and software. One technology that every designer should understand is the Common Object Request Broker Architecture (CORBA). CORBA is the required middleware layer for Software Communications Architecture (SCA)-based SDRs.

Commercial CORBA object request brokers (ORBs) are high-performance, small-footprint software products that provide the communications framework in single-processor and multiprocessor SDR systems. They promote the intelligent and optimal allocation of processing resources among GPPs, DSPs and FPGAs. Understanding the role of CORBA in these multiprocessor systems can save engineering resources, improve time-to-market, and increase performance and portability of small form factor SDRs.

In this article, Objective Interface Systems Inc.'s Joseph Jacob discusses more about CORBA in SDRs.
