摘要： A data transmission method for a universal serial bus (USB) host controller is provided. First, input data is received. A cyclic redundancy check (CRC) result of the input data is calculated, and, simultaneously, the input data is transmitted to a system memory of a host. Then, it is determined whether the input data is the last input data of a data packet. When it is determined that the input data is the last input data of the data packet, the CRC result of the last input data of the data packet is calculated. Thus, the CRC result of the data packet is accumulated. The accumulated CRC result is combined with the last input data, and transmitted the combination to the system memory of the host.

摘要： The present invention is directed to a universal serial bus (USB) transaction translator and an associated IN isochronous 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. A register is used to record device bus information. Before the host sends an IN packet, the controller pre-fetches data from the device according to the device bus information and then stores the data in the buffers; the controller responds with the pre-fetched data to the host after the host sends the IN packet.

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： A USB host controller is provided. The USB host controller is capable of communicating with multiple USB apparatuses having endpoints and sends a request to a first endpoint. The USB host controller includes a first storage and a first control unit. The first control unit stores endpoint information from the first endpoint into the first storage when the first endpoint issues an unready transaction packet in response to the request. The unready transaction packet indicates that the first endpoint is not ready.

摘要： A method for utilizing the multi-channel transmission bandwidth in an asymmetrically arranged memory is provides. The present invention defines symmetrically arranged parts of the memory ranks of the memory as a virtual ranks. If data is stored in symmetrically arranged memory ranks of the memory, channels corresponding to the symmetrically arranged memory ranks could be simultaneously utilized to transfer data. If data is stored in an asymmetrically arranged memory rank of the memory, the channel corresponding to the asymmetrically arranged memory rank could only be utilized to transfer data.
