Abstract
A queue circuit that manages access to a memory circuit in a computer system includes multiple sets of entries for storing access requests. The entries in one set of entries are assigned to corresponding sources that generate access requests to the memory circuit. The entries in the other set of entries are floating entries that can be used to store requests from any of the sources. Upon receiving a request from a particular source, the queue circuit checks the entry assigned to the particular source and, if the entry is unoccupied, the queue circuit stores the request in the entry. If, however, the entry assigned to the particular source is occupied, the queue circuit stores the request in one of the floating entries.
