    摘要： A scheduler performs a plurality of scheduler operations each scheduling an output queue selected from a plurality of output queues associated with an egress port. The scheduler includes a candidate decision logic and a final decision logic. The candidate decision logic is arranged to decide a plurality of candidate output queues for a current scheduler operation, regardless of a resultant status of packet transmission of at least one scheduled output queue decided by at least one previous scheduler operation. The final decision logic is arranged to select one of the candidate output queues as a scheduled output queue decided by the current scheduler operation after obtaining the resultant status of packet transmission of the at least one scheduled output queue decided by the at least one previous scheduler operation.

    摘要： A USB host controller is provided. The USB host controller includes an endpoint management unit, a transfer management unit, and a schedule management unit. The endpoint management unit manages endpoint configurations of a USB device, wherein the USB device includes a plurality of endpoints and the endpoint configurations include a plurality of statuses of the endpoints of the USB device. The transfer management unit transfers data regarding transfer information of the endpoints of the USB device between a system memory and the USB host controller. The schedule management unit simultaneously manages packet transfer of at least two endpoints of the USB device.

    摘要： One packet output controller includes a scheduler and a dequeue device. The scheduler performs a single scheduler operation to schedule an output queue selected from a plurality of output queues associated with an egress port. The dequeue device dequeues multiple packets from the scheduled output queue decided by the single scheduler operation. Another packet output controller includes a scheduler and a dequeue device. The scheduler performs a plurality of scheduler operations each scheduling an output queue selected from a plurality of output queues associated with an egress port. The scheduler performs a current scheduler operation, regardless of a status of a packet transmission of a scheduled output queue decided by a previous scheduler operation. The dequeue device dequeues at least one packet from the scheduled output queue decided by the current scheduler operation after the packet transmission of the scheduled output queue decided by the previous scheduler operation is complete.

    摘要： An active output buffer controller is used for controlling a packet data output of a main buffer in a network device. The active output buffer controller has a credit evaluation circuit and a control logic. The credit evaluation circuit estimates a credit value based on at least one of an ingress data reception status of the network device and an egress data transmission status of the network device. The control logic compares the credit value with a first predetermined threshold value to generate a comparison result, and controls the packet data output of the main buffer according to at least the comparison result.
