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. In another embodiment, the sending period of SOF packets may be dynamically adjusted in isochronous transfer.
摘要翻译：本发明涉及通用串行总线（USB）事务转换器和微帧同步方法。设备接口经由设备总线耦合到设备，并且主机接口通过主机总线耦合到主机，其中主机USB版本高于设备USB版本。配置为存储数据的至少两个缓冲器被布置在设备接口和主机接口之间。控制器交替地将数据存储在缓冲器中。使用起始帧（SOF）计数器对SOF分组进行计数，其中将SOF计数器的计数值与预定义的值进行比较。具体地，当计数值达到预定义值或大于预定值时，控制器复位用于发送SOF分组的SOF定时器，使得来自主机的SOF分组和等时时间戳分组（ITP）以相同的方式发送时间。此外，控制器根据来自主机的ITP延迟SOF分组的发送一段时间。在另一个实施例中，SOF分组的发送周期可以在等时传输中动态调整。
