  • Publication number: 20240045618
    Abstract: A host system is coupled to a storage device and manages completion queues (CQs) for the storage device. The host system includes a host controller and memory that stores submission queues (SQs) and the CQs. The host controller fetches a command from a given SQ that corresponds to a target CQ. The host controller saves the command in an SQ internal buffer of the host controller, calculates an available capacity (AC) associated with the given SQ for the host system to store a response to the command from the storage device, and sends the command to the storage device when the available capacity is non-zero. The available capacity is calculated based on, at least in part, available slots in the target CQ.

  • Patent number: 9674299
    Abstract: A standby agent apparatus includes an interface and a standby agent controller. The interface is arranged for receiving at least first account information of a first system. The standby agent controller is coupled to the interface. When the first system is operating in a standby mode, the standby agent controller is arranged for keeping an account of the first system on-line in a first application server according to the received first account information of the first system. A connection handling method includes the following steps: receiving first account information of a first system; and when the first system is operating in a standby mode, keeping an account of the first system on-line in a first application server according to the received first account information of the first system.

  • Publication number: 20100125689
    Abstract: The invention provides an electronic apparatus capable of receiving a first-type memory card or a second-type memory card. In one embodiment, the electronic apparatus comprises a socket, a controller circuit, and an interface circuit. The socket is coupled to the first-type memory card through a set of first pins and is coupled to the second-type memory card with a set of second pins. The controller circuit accesses the first-type memory card or the second-type memory card via a plurality of input/output (IO) pins, and determines which of the first-type memory card and the second-type memory card is inserted into the socket according to the voltage of a target IO pin selected from the IO pins. The interface circuit sets the voltage of the target pin to different values according to whether the first-type memory card or the second-type memory card is inserted into the socket.

  • Publication number: 20080100740
    Abstract: Methods for adjusting digital video signals, performed by an image generating device of a portable media player, are disclosed. A first signal adjustment unit reduces a resolution of a video frame to generate a reduced video frame by alternately dropping half of the scan lines of the video frame, and repeatedly drops scan lines after at least two scan lines until reaching the last scan line. The content of a first video frame is adjusted to a second video frame in response to a second signal adjustment unit before passing to the display module by the image generating device. The display module is directed to prevent adjustment of the second video frame by the first signal adjustment unit for generating a display video frame. The second video frame is adjusted by the second signal adjustment unit and output to the display module.
