摘要： In order to solve the technical problem that in the current real-time distributed systems such as multi-antenna MIMO system, the implementation of synchronization between distributed modules by means of software is of a large time overhead, the invention proposes a synchronization method and device for the real-time distributed system, the distributed module determines if the present module is able to operate synchronously, at a synchronization start time that is unified with the other distributed modules; sets the present module's operate indication signal in a logic circuit, based on the determining result; and decides whether the present module is to operate synchronously, following a rule unified with the other distributed modules, based on the present module's operate indication signal along with the operate indication signals in the logic circuit set by the other modules. The invention implements real-time synchronization between distributed modules by means of hardware logic circuit with small operation time overhead, and preferably it only needs several-bit logic circuit and several cascaded logic gates, the structure is concise, efficient, and easy to implement and extend.
