Rapid prototyping for DSP systems with multiprocessors

The authors describe the hardware and software of a system for prototyping digital-signal-processing applications by using commercially available digital-signal processors linked to form multiprocessors. The graphical programming environment makes it easier to program, compile, debug, and test DSP algorithms. The system reduces the cost of application prototyping, making it a feasible step at early design stages. To demonstrate the advantages of their approach, the authors explain how they prototyped a digital audio broadcast system. The complexities encountered highlight the limitations of the system.<>
