Abstract
An apparatus comprises a buffer comprising a plurality of entries, an insert pointer, a delete pointer, a plurality of first control circuits coupled to the buffer, and a second control circuit coupled to the buffer. The entries are logically divided into a plurality of groups. Each of the first control circuits corresponds to a respective group and selects an entry from the respective group for potential reading from the buffer. Furthermore, each of the first control circuits, in the event that the delete pointer indicates a first entry in the respective group and the insert pointer wraps around the buffer and indicates a second entry in the respective group, selects the first entry if the first entry is eligible for selection. The second control circuit selects a first group, and the entry selected from the first group by the first control circuits is the entry read from the buffer.
