Asynchronous stands for the absence of synchronization. In computing or telecommunication stream Asynchronous stands for controlling the operation timing by sending a pulse only when the previous operation is completed rather than sending it in regular intervals. Asynchronous logic design
Asynchronous Logic Design, Typical problems will be the design of ip-ops arbitraters synchronous switches and a variety of other sequential circuit blocks which are used in com-plex digital systems. The required number of logic gates to design asynchronous counters is very less. Providing an updated look at asynchronous circuit design in a form accessible to a student who simply has some background in digital logic design. The most aggressive form of circuit design uses timing assumptions both within and across blocks that must be.
