A Design Example Using Castle

CASTLE is a codesign platform which provides a number of design tools for configuring application specific design flows. This paper presents a walk through CASTLE’s codesign environment, following the design flow of a video processing system. The design methodology and the tool usage for this real life example are described, as seen from a designers point of view. The design flow starts with a C/C++ program and gradually derives a register-transfer level description of a processor hardware, as well as the corresponding compiler for generating the processor opcode. The main results of each design step are presented and the usage of the CASTLE tools at each step is explained.
