This demonstration presents an integrated environment that translates a CAL-based dataflow specification [1] into a heterogeneous implementation, composed by HDL and C codes. The demonstration focuses on the capability of the co-design environment to automatically build an executable heterogeneous system implementation running on a platform composed of a processor and a FPGA from the annotation of the CAL specification. The possibility of direct synthesis from a high level specification is a crucial issue for enabling efficient re-design cycles that include rapid prototyping and validation of performances of the final implementation. The design approach enabled by such integrated environment is particularly suited for development of complex processing systems such as video codecs. As a case study, the demonstration provides the analysis and validation of different software and hardware partitioning of a MPEG-4 simple profile decoder.
