Reconfigurable event driven hardware using reservoir computing for monitoring an electronic sensor and waking a processor

An energy constrained system comprising:

• (a) a primary processor having a low power consumption mode, the primary processor being configured to respond to a plurality of trigger signatures, each trigger signature classifying one or more predetermined sensed conditions, by
• (i) exiting the low power consumption mode;
• and
• (ii) invoking a software routine to initiate an action specific to a trigger signature received by the primary processor;
• (b) an electronic sensor adapted to continuously provide a sensor output that reflects a presently sensed condition;
• and
• (c) reconfigurable event driven hardware coupled between the primary processor and the electronic sensor, the reconfigurable event driven hardware receiving the sensor output, the reconfigurable event driven hardware being implemented using reservoir computing including:
• (i) a capturing element configured to capture a temporal behavior of the sensor output;
• and
• (ii) a classifying element configured to classify an output of the capturing element including the temporal behavior to identify a trigger signature,
• wherein the primary processor is operable to configure the reconfigurable event driven hardware to detect the plurality of trigger signatures,
• wherein the reconfigurable event driven hardware is, adapted to continuously monitor the sensor output to detect a trigger signature from among the plurality of trigger signatures, and
• wherein the reconfigurable event driven hardware is further adapted to communicate the trigger signature to the primary processor without communicating the one or more predetermined sensed conditions, in response to a detection of a trigger signature while the primary processor is in the low power consumption a mode.
