Patent number: 9009380Abstract: A universal serial bus (USB) transaction translator is provided along with 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. At least two buffers are configured to store data. A controller stores the data in the buffers alternately. A start-of-frame (SOF) counter is used to count the SOF packets, with the counting value of the SOF counter being compared to a predefined value. Specifically, the controller resets a SOF timer for sending the SOF packet when the counting value achieves or exceeds 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.Type: GrantFiled: September 26, 2013Date of Patent: April 14, 2015Assignee: VIA Technologies, Inc.Inventors: Jiin Lai, Chin-Sung Hsu, Terrance Shiyang Shih, Jinkuan Tang, Buheng Xu, Hui Jiang

Patent number: 8930599Abstract: A data transmission system and method are provided. The data transmission method receives a second format data packet sent by a host; decodes the second format data packet sent by the host, and translating the decoded second format data packet into a first format data packet; transmits the first format data packet to a first device; receives a transmission response sent by the first device in response to the first format data packet, determines whether to transmit the transmission response to the host, and performs a re-try flow when the transmission response does not need to be transmitted to the host. Preferably, a data transmission rate of the first device is slower than that of a second device, and the data transmission system is backward compatible to the first device, and the second format data packet is consistent with the second device.Type: GrantFiled: October 8, 2013Date of Patent: January 6, 2015Assignee: Via Technologies, Inc.Inventors: Jiin Lai, Buheng Xu, Jinkuan Tang

Patent number: 8656074Abstract: A data transmission system is provided. The data transmission system includes a first control circuit coupled to a first device, a translation circuit coupled to the first control circuit and a second control circuit coupled to the translation circuit. The first control circuit decodes a first format data packet sent by the first device. The translation circuit receives the decoded first format data packet and translates the decoded first format data packet into a second format data packet. The second control circuit transmits the second format data packet to a host. A data transmission rate of the first device is slower than that of a second device, and the data transmission system is backward compatible to the first device.Type: GrantFiled: August 24, 2010Date of Patent: February 18, 2014Assignee: Via Technologies, Inc.Inventors: Jiin Lai, Buheng Xu, Jinkuan Tang

Patent number: 8549184Abstract: 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.Type: GrantFiled: December 2, 2010Date of Patent: October 1, 2013Assignee: VIA Technologies, Inc.Inventors: Jinkuan Tang, Jiin Lai, Buheng Xu, Hui Jiang
