    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.

    Abstract translation: 通过将执行指令调度到多个执行单元来降低微处理器峰值功率的方法。 在现有技术中,通过大功率执行单元的指令的并行处理使得微处理器的峰值功率增加。 本发明的方法尝试通过确保两个高功率执行单元不同时执行来降低微处理器的峰值功率。 当由第一执行单元执行第一指令时,第一信号被断言。 当第一信号被断言时,防止第二指令被分派到第二执行单元。 因此,第一执行单元执行第一指令时,第二执行单元保持空闲状态。
