Model-based architectural design and verification of scalable embedded DSP systems-a RASSP approach
The paper describes how rapid model-year architectural synthesis (e.g., HW/SW codesign) of embedded signal processors can be performed to optimize various cost objective functions using a reuse library of model, followed by simulation based optimization. Sponsored as part of DARPA's RASSP program, this approach has developed and released a number of interoperable and verified architectural component libraries at the system level (processors, communication protocols, and topologies). While these libraries have been used in actual demonstrations of avionics and military systems, such as the MIT Lincoln Laboratory's SAR Benchmark, the F-14 legacy Infrared Search and Track System (IRST), and as part of NASA/JPL's Remote Exploration/Experimentation (REE) program studies, the authors introduce the methodology of conceptual prototyping and establish the requirements and features of the proposed environment. They also illustrate its use on some common applications with relatively sophisticated architectural building blocks, such as IEEE SCI protocol and Analog Devices' SHARC processor family.
