1. An apparatus for detonation control in spark ignition engines, the apparatus comprising:
an analog neuromorphic hardware device trained to detect early detonation in cylinders of a spark ignition engine;
a knock sensor coupled to the spark ignition engine;
an ignition coil for the spark ignition engine; and
an Electronic Control Unit (ECU) for the spark ignition engine;
wherein the analog neuromorphic hardware device is configured to:
receive knock sensor signals from the knock sensor;
receive ignition coil data from the ignition coil;
determine a knock level and ignition quality measure based on the received knock sensor signals and the received ignition coil data; and
transmit the knock level and ignition quality measure to the ECU.
