SYNCHRONOUS TRANSMISSION DEVICE AND SYNCHRONOUS TRANSMISSION METHOD

摘要

A synchronous transmission device includes a first communication port, a first bus instance and a second bus instance. The first communication port is connected to the first endpoint and the second endpoint. The first bus instance executes a first data transmission with the first endpoint according to a first node of a first schedule list. The first node corresponds to the first endpoint, and the first bus instance corresponds to the first communication port. When the first data transmission is executed, the first bus instance is further configured to determine whether the second bus instance is idle. When the second bus instance is idle, the first bus instance controls the second bus instance to execute a second data transmission with the second endpoint according to a second node of the first schedule list. The second node of the first schedule list corresponds to the second endpoint.
