Abstract
Systems and methods for determining dependencies between processor instructions in multiple phases. In one embodiment, a partial comparison is made between the addresses of a sequence of instructions. Younger instructions having potential dependencies on older instructions are suspended if the partial comparison yields a match. One or more subsequent comparisons are made for suspended instructions based on portions of the addresses referenced by the instructions that were not previously compared. If subsequent comparisons determine that the addresses of the instructions do not match, the suspended instructions are reinstated and execution of the suspended instructions is resumed. In one embodiment, data needed by suspended instructions is speculatively requested in case the instructions are reinstated.
