Classification: CPC G  B | IPC G

Claim 5:
6. A vehicle, comprising:
a plurality of controls for steering, braking, and acceleration;
a set of sensors configured to generate a sensor data stream;
a lidar sensor comprising:
a generator of lidar images;
a memory configured to store a lidar image and an artificial neural network;
an inference engine configured to use the artificial neural network to analyze the lidar image and generate inference results; and
a communication interface;

a computer system coupled to the communication interface to implement an advanced driver assistance system to operate the controls according to the inference results and the sensor data stream;
wherein the memory includes a first predefined region configured to store a model of the artificial neural network, a second predefined region configured to receive neuron inputs, and a third predefined region configured to store neuron outputs;
wherein generation of the neuron outputs in the third predefined region is configured according to the model in response to the lidar image being written into the second predefined region;
wherein the inference engine includes a memristor crossbar array configured to perform matrix multiplication and accumulation operations; and
wherein memristors in the crossbar array are configured to store parameters of the artificial neural network; and the multiplication and accumulation operations are performed by the memristors converting voltages on wordlines of the crossbar array into currents summed in bitlines of the crossbar array.
