Abstract:

A computational model of event based on asynchronous dataflow (EADF) and its formal description are presented. This model has been independently implemented in dataflow visual programming language, LabScene2.0 which can develop virtual instruments. Simulation System of Nuclear Magnetic Resonance Instrument Searching for Water is taking an example to analyze and explain. DFVPL based on EADF has reduced the design of parallel for programmer and the performance has greatly improved in statically scheduled loop, great amount of computation and resource achieving in net or local system I/O.

Key words: computer software, dataflow, computational model, dataflow visual programming language, virtual instruments
