System Level Specification for Multimedia Applications
Dohyung Kim, Soonhoi Ha · 2003
This paper presents a system level specification for codesign of control modules and function modules in multimedia applications which have significant computational requirements as well as complex control systems. In the proposed compositional approach, control modules and function modules are separately described with extended FSM, called fFSM, and dataflow respectively, and integrated in the top-level codesign backplane. The codesign backplane supports interaction requirements between control and function modules, enables cosimulation of their composition, and will provide cosynthesis. Since fFSM and dataflow models are formal models of computation, we can analyze the specification of each module. Comparison with previous approaches and preliminary experiments show novelty and practicality of the proposed technique.
