Abstract
A unified buffer, comprising a shifting queue, receives instructions to be tracked by receiving units in a computer architecture. The receiving units search the unified buffer from the oldest entry to the most recent entry. Status bits in each entry indicate which of the receiving unit(s) the entry is destined for. Existing entries in the unified buffer shift down when a new entry is inserted at the top. Entries may be passed to different receiving units by updating the status bits; and an entry expires after it has been accepted by its final receiving unit.
