Abstract

See full text

In an embodiment, a system on a chip (SOC) includes a component that remains powered when a central processing unit (CPU) processor and a memory controller of the SOC are powered off. The component may include a sensor capture unit to capture audio samples from an audio detector circuit and write them to a memory of the component. A processor of the component may be configured to search the audio samples for a predetermined pattern during a time when the CPU processor and the memory controller are powered down. In some embodiments, based on the audio samples filling to a threshold level in the memory of the component and a lack of detection of the predetermined pattern, the component is configured to wake up the memory controller and a path to the memory controller in order to write the audio sample to a memory controlled by the memory controller.
