Abstract: In a first aspect, a method is provided for conserving power in a processing integrated circuit. This method includes the steps of calculating (401-408) power consumption for executing an instruction and data corresponding to the instruction; and executing (409, 410) the instruction if such execution does not exceed a predetermined power level. In a second aspect, a method is provided for conserving power in a processing integrated circuit employing a plurality of execution units. The method includes the steps of comparing (301, 302) a total power to be consumed by the processing integrated circuit to a power budget for the processing integrated circuit; and if the total power exceeds the power budget, freezing (304) execution of an instruction by one of the plurality of execution units so as to allow execution of the instruction to continue at a later time from where execution waSt frozen. Numerous other aspects are provided, as are systems and apparatus.

Abstract translation: 在第一方面，提供了一种用于在处理集成电路中节省功率的方法。 该方法包括计算（401-408）用于执行指令的功耗和对应于该指令的数据的步骤; 以及如果所述执行不超过预定功率电平则执行（409,410）所述指令。 在第二方面，提供一种用于在采用多个执行单元的处理集成电路中节省功率的方法。 该方法包括以下步骤：将处理集成电路要消耗的总功率（301,302）与处理集成电路的功率预算进行比较; 并且如果所述总功率超过所述功率预算，则通过所述多个执行单元中的一个来执行指令的冻结（304），从而允许执行所述指令在从执行waSt被冻结的较后时间继续执行。 还提供了许多其他方面，系统和装置也是如此。
