Abstract
A parallel processing-based time synchronization apparatus employs a double-filter structure based on parallel processing, providing more precise and reliable time synchronization between a master device and a slave device. A first filter is implemented as hardware so as to realize time synchronization despite cyclic synchronization message transmission at short intervals and the second filter is implemented as software so as to realize precise time synchronization.
