Samsung patents sensor hub that wakes main processor based on data patterns

Patent drawing from the official filing.

Samsung describes a small chip called a context hub that collects data from various sensors on a device. It looks for specific patterns in this data to decide when to wake up the main processor and how much power to use.

Why it mattersThis design could help phones and other devices save battery by keeping the main processor asleep until important sensor patterns are detected.

In the filing’s own words

A context hub receives and processes data from multiple sensors. An operation method of the context hub includes identifying a pattern of context data input to the context hub from at least one of the sensors, determining a dynamic voltage-frequency scaling (DVFS) level corresponding to the identified pattern of the context data, and processing, at the context hub, the context data by using a clock signal or a driving voltage corresponding to the determined DVFS level.

What exactly they claim (claim 1)

1. An electronic device, comprising: a plurality of sensors configured to generate context data; a context input pattern information circuit configured to store context input pattern information; a main processor; and a context hub configured to: receive the context data from the plurality of sensors; identify a pattern of the context data; read the context input pattern information from the context input pattern information circuit based on the identified pattern; and trigger the main processor based on the context input pattern information.
