Abstract
Asynchronous stream generation and processing techniques are described that support implementation of an asynchronous stream mote in which one or more analog sensor signals are used to generate one or more asynchronous streams. On-device operations processing of the one or more asynchronous streams may be performed before transmission of the result(s) to other system components (e.g., peer motes or higher-level system components).
Claims16
A device, comprising:
- first asynchronous stream generator circuitry configured to receive an analog signal and to generate an asynchronous stream representing the analog signal, the asynchronous stream representing a magnitude of the analog signal as a stream of values in which a duty factor of the stream of values is based on the magnitude of the analog signal;
- one or more asynchronous stream processors configured to receive a first one or more asynchronous streams generated by the first asynchronous stream generator circuitry and to generate one or more results;
- an analog memory having stream processing information stored therein for use by the one or more asynchronous stream processors in generating the one or more results;
- second asynchronous stream generator circuitry configured to provide the stream processing information from the analog memory to the one or more asynchronous stream processors as a second one or more asynchronous streams;
- and
- a transmitter configured to wirelessly transmit a signal representing the one or more results.
