Assessing and improving current practice in the design of application-specific signal processors

The Department of Defense ARPA program for Rapid Prototyping of Application Specific Signal Processors (RASSP) exists to significantly improve the process by which embedded digital signal processors are developed (prototyped) and supported (maintained and upgraded). As used in the RASSP program, the term prototype signifies a system that is a precursor to a deployed system, but still meets all of the essential performance goals and is designed to facilitate maintainability and upgradability. Current practice in the design of embedded digital signal processors, as exemplified in the traditional waterfall design methodology, is examined and shortfalls in the design, methodology and supporting tools are identified. Opportunities for improving the traditional design practice are then identified and evaluated in terms of potential benefits, as well as impediments, to implementation, and adoption by the community.
