Asynchronous circuit design

摘要

There are two standpoints in asynchronous circuit design. From one standpoint how to analyze an asynchronous circuit is main interest. From the other standpoint how to construct a large asynchronous circuit is main interest. Recently, from the latter a good design methodology for asynchronous circuits design has been established. This consists of a handshake communication and 2 phases dual-rail logic. This paper gives an overview of these techniques, and points out the fact that arbitration is necessary for low power consumption.
