A hardware-software codesign methodology for DSP applications

The authors describe a systematic, heterogeneous design methodology using the Ptolemy framework for simulation, prototyping, and software synthesis of systems containing a mixture of hardware and software components. They focus on signal-processing systems in which the hardware typically consists of custom data paths, finite-state machines (FSMs), glue logic and programmable processors. The software is one or more embedded programs running on the programmable components.<
