摘要： The present invention is directed to a universal serial bus (USB) transaction translator and an associated IN/OUT bulk transaction method. A device interface is coupled to a device via a device bus, and a host interface is coupled to a host via a host bus, wherein the host USB version is higher than the device USB version. At least two buffers configured to store data are disposed between the device interface and the host interface. A controller stores the data in the buffers alternately. In a bulk-IN transaction, before the host sends an IN packet, the controller pre-fetches data and stores the data in the buffers until all the buffers are full or a requested data length has been achieved; the pre-fetched data are then sent to the host after the host sends the IN packet. In a bulk-OUT transaction, the controller stores the data sent from the host in the buffers, and the data are then post-written to the device.

摘要： The present invention is directed to a universal serial bus (USB) transaction translator and a micro-frame synchronization method. A device interface is coupled to a device via a device bus, and a host interface is coupled to a host via a host bus, wherein the host USB version is higher than the device USB version. At least two buffers configured to store data are disposed between the device interface and the host interface. A controller stores the data in the buffers alternately. A start-of-frame (SOF) counter is used to count the SOF packets, wherein the counting value of the SOF counter is compared to a predefined value. Specifically, the controller resets a SOF timer for sending the SOF packet when the counting value achieves the predefined value or is greater than the predefined value, such that the SOF packet and an isochronous timestamp packet (ITP) from the host are sent at the same time. Further, the controller delays the sending of the SOF packet for a period of time according to the ITP from the host.

When the first link partner is in an abnormal operation mode, the controller controls the first link partner to exit from the abnormal operation mode. The optical transceiver unit is coupled between the first link partner and a second link partner and performs data transmission between the first link partner and the second link partner. According to the data transmission system and method, one link partner can accurately detect whether another link partner is coupled to the one link partner through an optical transceiver unit. Accordingly, data transmission between the two link partners can be stably performed through the optical transceiver unit.
