Abstract
A method for generating an asynchronous controller includes a process controller formation step S of forming a signal transition graph representing a state of change in input/output signals of a plurality of process controllers PC PC for outputting control signals necessary for executing a process corresponding to a node in a data flow graph showing a performance sequence between a plurality of nodes each representing a process and a plurality of processes, a process sequencing controller formation step S of forming a signal transition graph of a process sequencing controller PSC according to a performance sequence of the process controllers PC PC from the data flow graph, and a logic synthesis step S of generating an asynchronous controller in a logic synthesis program, by using the state of change in the input/output signals on the signal transition graph of the process controllers PC ˜PC formed in the process controller formation step S and the state of change in the input/output signals on the signal transition graph of the process sequencing controller PSC formed in the process sequencing controller formation step S . The asynchronous controller is divided into the process controller and the process sequencing controller, which provides advantages in an area, performance and a synthesis time.
