Low Power Management of Multiple Sensor Chip Architecture

A system, comprising:

• a first processor operatively coupled to a first sensor;
• a second processor operatively coupled to the first processor and a second sensor;
• a third processor operatively coupled to the second processor;
• wherein the first processor is configured to:
• receive first sensor data from the first sensor;
• determine a motion state of the system using the first sensor data;
• and
• in response to determining that the motion state corresponds to a predetermined motion state, activate the second processor;
• wherein the second processor is configured to:
• receive second sensor data from the second sensor;
• and
• determine that the motion state corresponds to the predetermined motion state using the second sensor data;
• and
• wherein in response to determining that the motion state corresponds to the predetermined motion state using the second sensor data, sending the motion state to the third processor.

A method, comprising:

• at a computing device having a first processor, a second processor and a third processor;
• receiving, at the first processor, first sensor data from a first sensor;
• determining, at the first processor, that the computing device has changed from being stationary to being in motion using the first sensor data;
• in response to determining that the computing device has changed, activating, by the first processor, the second processor;
• determining, by the second processor, a motion state of the computing device using the first sensor data;
• in response to determining the motion state of the computing device, activating the third processor;
• and
• sending the motion state to the third processor.

A method, comprising:

• at a computing device that includes a first processor, a second processor and a third processor,
• performing, at the first processor, an algorithm using a first level of confidence associated with a first sensor;
• in response to determining that a second level of confidence associated with a second sensor is needed, activating the second processor;
• determining, by the second processor, a result of the algorithm using the second level of confidence associated with the second sensor;
• and
• in response to determining that the result of the algorithm corresponds to a predetermined result, sending the result of the algorithm to the third processor.
