    Abstract: An SOC includes a secure processor and an always-on component. The always-on component may remain powered even during times that other parts of the SOC are powered off. Particularly, the secure processor and related circuitry may be powered off, while various state for the secure processor may be stored in memory in an encrypted form. Certain state may be stored in the always-on component. When the secure processor is powered on again, the secure processor may check for the state in the always-on component. If the state is found, the secure processor may retrieve the state and use the state to access the encrypted memory state.

    Abstract translation: SOC包括一个安全处理器和一个永远在线的组件。 即使在SOC的其他部分断电的时间内，始终在线的组件也可能保持供电。 特别地，安全处理器和相关电路可以被断电，而用于安全处理器的各种状态可以以加密形式存储在存储器中。 某些状态可能存储在始终在线的组件中。 当安全处理器再次通电时，安全处理器可以检查始终打开组件中的状态。 如果发现状态，则安全处理器可以检索状态并使用该状态来访问加密的存储器状态。

    Abstract: In an embodiment, a system on a chip (SOC) includes a component that remains powered when the remainder of the SOC is powered off. The component may include a sensor capture unit to capture data from various device sensors, and may filter the captured sensor data. Responsive to the filtering, the component may wake up the remainder of the SOC to permit the processing. The component may store programmable configuration data, matching the state at the time the SOC was most recently powered down, for the other components of the SOC, in order to reprogram them after wakeup. In some embodiments, the component may be configured to wake up the memory controller within the SOC and the path to the memory controller, in order to write the data to memory. The remainder of the SOC may remain powered down.
