DSP-Based System Design in the Ptolemy Environment

General-purpose digital signal processors (DSPs) are programmable devices with sufficient flexibility to have a variety of systems applications. Recently, the performance of DSPs has improved enough that they are being applied in video signal processing. Such DSPs are good candidates for multi-media systems, which process data, speech and video signals.

The aim of this research is to implement DSP-based system design procedures in the Ptolemy environment. The procedure consists of simulation, to verify and tune algorithms, and code generation for target DSPs. In the design process, the computational complexity of the designed system must be carefully considered to meet the DSP performance demands. Video signal processing systems, such as video codecs, which have high computation demands, are chosen as the first example.
