More Information
Summary:This invention relates generally to detection of misfires in automotive internal combustion engines and, more particularly, to a bit-serial based recurrent neuroprocessor for processing data from an internal combustion engine in order to diagnose misfires in automotive engines in real-time. An engine diagnostic system includes a bit-serial based recurrent neuroprocessor for processing data from an internal combustion engine in order to diagnose misfires in real-time and reduces the number of neurons required to perform the task by time multiplexing groups of neurons from a candidate pool of neurons to achieve the successive hidden layers of the recurrent network topology.
