The virtual finite-state machine design and implementation paradigm

摘要

This paper discusses the virtual finite-state machine (VFSM) design and implementa- tion paradigm and our experience in introducing VFSM on software development projects for several Lucent Technologies products. VFSM, which allows software developers to specify the control behavior of a module as a finite-state machine, is supported by a toolset that automates many tasks associated with producing an implementation, including aspects of code generation, documentation, and testing.
