Abstract :
We propose a rapid-prototyping setup to minimize development cost and a structured-prototyping methodology to reduce programming effort. The general-purpose hardware consists of commercial DSP processors, bond-out versions of core processors, and field-programmable gate arrays (FPGAs) linked to form a powerful, heterogeneous multiprocessor, such as the Paradigm RP developed within the Retides (Real-Time DSP Emulation System) Esprit project. Our Graphical Rapid Prototyping Environment (Grape-II) automates the prototyping methodology for these hardware systems by offering tools for resource estimation, partitioning, assignment, routing, scheduling, code generation, and parameter modification. Grape-II has been used successfully in three real-world DSP applications
