A Control Circuit Synthesis Method for Asynchronous Circuits in Bundled-Data Implementation

This paper proposes a control circuit synthesis method for asynchronous circuits in bundled-data implementation. Our proposed method consists of the synthesis of a con- trol circuit to control a data-path circuit and the synthesis of an interface circuit between the control circuit and the data-path circuit. The control circuit is generated by map- ping small control elements called Q-elements. For map- ping, this paper proposes two mapping methods called the state-oriented mapping method and the node-oriented map- ping method. Finally, this paper shows the effectiveness of the proposed method by comparing synthesized circuits with ones obtained by a different control circuit synthesis method.
