Synchronous data transfer system using time stamp

摘要

There is provided a data transfer system over a plurality of nodes each having an internal oscillating circuit to generate a clock signal. The plurality of the nodes are connected to one another through a communication network and operate asynchronously with one another according to the respective clock signals. One of the nodes supplies a synchronization signal indicative of a reference time to the communication network. The plurality of the nodes include a transmitting node that transmits a train of data having a time-sequential arrangement together with time data indicative of a time lag relative to the reference time, and a receiving node that receives the train of dada together with the time data by which synchronous communication of the train of data can be ensured between the transmitting node and the receiving node.
