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： Resuming from a sleep state. A request may received to resume operation of a computer system from a sleep state to an executing state. A restoring process may be initiated to restore the computer system to an executing state. The restoring process may include loading information from a nonvolatile memory medium to a computer system memory medium. A request may be received from a processor of the computer system to access the computer system memory medium. The request may require access to a portion of the computer system memory medium in the executing state, and may be received prior to completion of the restoring process. It may be determined if the portion of the computer system memory medium has been restored. If the portion of the computer system memory medium has not been restored, the portion of the computer system memory medium may be restored from the nonvolatile memory medium ahead of other portions in the restoring process.

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： A computer system having low-power operation includes a controller in communication with a first storage device and a second storage device. The controller can be configured to periodically retrieve dynamic frame data from a first storage device during a time period when the computer system is not in an idle state. During a time period when the computer system is in an idle state, the controller is configured to store static frame data into a second storage device, and repeatedly retrieve the static frame data from the second storage device to display an image represented by the static frame data during a time when the computer system continues to be in the idle state.
