ABSTRACT:
A method of reducing microprocessor peak power by scheduling execution of instructions to multiple execution units. In the prior art, parallel processing of instructions by high-power execution units caused the microprocessor peak power to increase. The method of the present invention attempts to reduce microprocessor peak power by ensuring that two high-power execution units are not executing simultaneously. While a first instruction is being executed by a first execution unit, a first signal is asserted. A second instruction is prevented from being dispatched to a second execution unit while the first signal is asserted. Thus, the second execution unit remains in an idle state while the first execution unit is executing the first instruction.
