Abstract
Although many successful asynchronous control circuit synthesis methods are available, it is still unwieldy to conceive mid describe the behaviors of a number of controllers which constitute a control unit of a target system manually. In this paper. an automatic and systematic method to derive an ef ficient asynchronous control unit front a system specification, a control d ata How graph (CDFG). is suggested. In order to acquire an asynchronous con trol unit of acceptable quality, a new process-oriented method is proposed. In this method, the resulting asynchronous control unit has complete separ ation of 'execution controllers' and 'execution order controllers' accordin g to the hierarchical decomposition of a given CDFG. This distributive feat ure leads to a significant improvement in area. performance, implementabili ty arid synthesis tina, for the derived asynchronous control units.
