    Abstract: Technologies for local power gate (LPG) interfaces for power-aware operations are described. A system on chip (SoC) includes a first functional unit, a second functional unit, and local power gate (LPG) hardware coupled to the first functional unit and the second functional unit. The LPG hardware is to power gate the first functional unit according to local power states of the LPG hardware. The second functional unit decodes a first instruction to perform a first power-aware operation of a specified length, including computing an execution code path for execution. The second functional unit monitors a current local power state of the LPG hardware, selects a code path based on the current local power state, the specified length, and a specified threshold, and issues a hint to the LPG hardware to power up the first functional unit and continues execution of the first power-aware operation without waiting for the first functional unit to be powered up.

    Abstract translation: 描述了用于功率感知操作的本地电源门(LPG)接口的技术。 片上系统(SoC)包括耦合到第一功能单元和第二功能单元的第一功能单元,第二功能单元和本地电源门(LPG)硬件。 LPG硬件根据LPG硬件的本地电源状态为第一个功能单元供电。 第二功能单元解码执行指定长度的第一功率感知操作的第一指令,包括计算用于执行的执行代码路径。 第二功能单元监视LPG硬件的当前本地电源状态,根据当前本地电源状态,指定长度和指定的阈值选择代码路径,并向LPG硬件发出提示,以启动第一个功能 并且继续执行第一功率感知操作,而不等待第一功能单元被加电。
