ABSTRACT:
Method and system for controlling the dynamic latency of an arithmetic logic unit (ALU). In one embodiment, the identification of the destination operand of an instruction is stored in a temporary register ID/thread control ID pair pipeline if the destination operand is a temporary register. Furthermore, each source operand of an instruction is checked against the identifications stored in a group of temporary register ID/thread control ID pipelines. If a source operand is matched to an identification stored in the temporary register ID/thread control ID pipelines, the ALU does not execute the instruction until the matched identification is no longer matched in the pipelines.
