Automatic distributed asynchronous control circuit generation from data flow graph for asynchronous high-level synthesis

As an asynchronous design style becomes popular, the request for asynchronous high-level synthesis (AHLS) tools is increasing continuously. In this paper, a method to derive distributed asynchronous control circuits in an automatic and systematic manner is suggested as a part of an AHLS tool. In order to acquire control circuits with competent quality, a process-oriented method is proposed. Experimental results show that the suggested method is efficient in the aspects of area and performance of the derived control circuits.
