Synchronization of sensor output samples

A system comprising:

• a plurality of sensor controllers, wherein each sensor controller of the plurality of sensor controllers is configured to implement a respective decimation filter that is configured to generate a single sample output from multiple input samples generated by a corresponding sensor of a plurality of sensors, wherein a non-master sensor controller of the plurality of sensor controllers is configured to perform operations comprising:
• while monitoring for a sync signal from a master sensor controller of the plurality of sensor controllers, receiving and storing, by the non-master sensor controller of the plurality of sensor controllers, a plurality of input samples from the corresponding sensor;
• upon receiving the sync signal from the master sensor controller, generating, by the non-master sensor controller, a sample output representative of the plurality of input samples received by the sensor while monitoring for the sync signal, wherein generating the sample output comprises applying the respective decimation filter of the non-master sensor controller to the plurality of input samples;
• and
• outputting, by the non-master sensor controller, the sample output generated from the plurality of input samples received while monitoring for the sync signal from the master sensor controller.
