英文摘要：

Asynchronous design methodology has become one of the most promising directions in SOC design because asynchronous circuit possesses the advantages of low power, low noise, no clock skew, high robust and modularization. A comparison of synchronous system and asynchronous system has been presented. Several modules of asynchronous system have been introduced and data-transfer modes are discussed. Based on the implementation of the asynchronous modules, the structures, features, data signal type and application of asynchronous circuit signal transmission have been studies. Then, the principle of choosing module in practice has been given.
