Abstract
Queues are scheduled for outputting data using a hierarchical tree. Each level of the hierarchical tree includes multiple entries for storing status information associated with the queues. For example, a given entry of the tree stores multi-parameter status information associated with a corresponding queue to be serviced. To determine which of the queues is next in line for servicing, a logic circuit compares the multi-parameter status information stored in two or more entries of the tree. The next scheduled queue or highest priority queue in the tree is then serviced by outputting at least some of its data.
