1. A computing device comprising:
a vision sensor configured to generate vision sensor data;
an ambient computing system configured to repeatedly process the vision sensor data generated by the vision sensor according to a low-power detection process, and
when a detection is indicated by the low-power detection process, to wake one or more other components of the computing device to perform a high-power detection process using the vision sensor data; and
a main machine learning engine having a plurality of compute tiles, wherein the device is configured to perform the high-power detection process using the main machine learning engine.
