Abstract
Disclosed herein is a method for matching dependency coordinates and an efficient apparatus for performing the dependency coordinate matching very quickly. A plurality of buffers to store instructions is set forth. Each storage location of a buffer corresponds to a particular pair of dependency coordinates. Dependency matching logic receives the dependency coordinates for a buffered instruction and scheduling information pertaining to dispatched instructions. The dependency matching logic indicates whether a dependency precludes scheduling of the corresponding buffered instruction. Dependency checking logic produces a ready signal for the buffered instruction when no such dependency is indicated by the dependency matching logic.
