RETRACTED: The design and synthesis using hierarchical robotic discrete-event modeling (Retracted Article)

The design and implementation of a real-time complex system mostly require a complicated design process with many sophisticated software and hardware design tasks. It is valuable to develop a systematic approach to rapidly realize the complex system for embedded applications. In this paper, a methodology is proposed dedicated to the rapid hardware synthesis of an embedded, real-time complex system. By way of hierarchical and modular formalization, a complex system is decomposed into a set of distributed functional modules. The behavior of each module is represented as a discrete-event system (DES). The graphical language GRAFCET is adopted to model the individual DES module and then the hierarchical, pipelined behaviors of system. Finally a set of VHDL synthesis rules are applied to in order to generate VHDL-target efficient hardware for all modules and pipelining controller. As a demonstrative application, an efficient fuzzy system hardware is rapidly designed and synthesized via the proposed methodology. The proposed methodology is advantageous for the hardware implementation of embedded, real-time complex system with consistent and ensured quality.
