| Outline of Final Research Achievements |
Transition signaling asynchronous circuits work based on the transitions of request and acknowledgement signals. Such a design methodology has potential to implement high performance circuits, but also requires specialized design techniques, which has prevented this approach from becoming popular among designers. In this research project, we utilize new and special flip-flops that have multiple clock inputs for the same outputs, and we provide new design method based on templates using them, in order to make it possible for even designers without specialized design techniques to easily implement transition signaling asynchronous circuits. An asynchronous NoC router has been designed for demonstrating the proposed method. Furthermore, this idea has been extended to an asynchronous reconfigurable device that contains those special flip-flops in a configurable logic block. Its naive version has been evaluated by simulation, and we have concluded that such an approach is promising.
