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.

Abstract: A method and apparatus for managing power consumption in logic modules without causing power surges. A first and second logic module operate in response to a first and second clock signal, respectively, to carry out a command. When the command arrives, the first logic module begins to operate and indicates that it is busy. After a first delay, the second module begins to operate and indicates that it is busy. When both modules are finished and no new command is available, the busy indicators are deactivated and after a second delay the first clock signal is deactivated. A third delay after the first clock signal is deactivated, the second clock is deactivated. The first, second and third delays are programmable to avoid power surges in the respective modules.
