Claim 10:
11. A method, comprising:
generating, by a lidar sensor, lidar images;
storing, in memory of the lidar sensor, at least one lidar image and an artificial neural network, 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, and 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;
analyzing, by an inference engine of the lidar sensor, the lidar image using the artificial neural network to generate inference results, 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; and
communicating, by an interface of the lidar sensor, the inference results to a computer system of a vehicle, wherein the computer system is configured to generate control signals for autonomous driving of the vehicle based on the inference results and a sensor data stream generated by sensors configured on the vehicle.
