Example text

These four layers, however, are conceptual anchors that help organize the process of evolving the software radio architecture. One current evolutionary step, for example, is the integration of CORBA [31] into software radio architecture. The Object Management Group (OMG) has defined an Interface Definition Language (IDL) in their Common Object Request Broker Architecture (CORBA). CORBA [34] was developed primarily to define interfaces among software modules that were not originally designed to work together.

The software will not port well (and may not port at all) if special features of the platform beyond the reference set are used. The specification of a minimum level of capability for each parameter defines a reference platform for a family of software radio implementations. , traffic and control), and baseband digital processing capability. By 2010, most deployed radio platforms could be defined in terms of broadband RF access, several simultaneous channels supported, and moderate IF digital processing bandwidth.

An accurate estimate of the processing demand of software modules must be balanced against the realizable processing capacity of reprogrammable processor configurations. , SPECmarks [46]), the processing capacity of the reference platform will be well-defined. In addition, sustaining the required data rates across interprocessor interfaces can also be problematic. The tradeoff between large block sizes for efficient data transfer competes with radio applications’ needs for low latency. Thus, the reference platform must specify any algorithmic relationship among critical parameters such as interconnect bandwidth and data-transfer block size.
