A system and corresponding method for autonomous driving of a vehicle are provided. The system comprises at least one neural network (NN) that generates at least one output for controlling the autonomous driving. The system further comprises a main data path that routes bulk sensor data to the at least one NN and a low-latency data path with reduced latency relative to the main data path. The low-latency data path routes limited sensor data to the at least one NN which, in turn, employs the limited sensor data to improve performance of the at least one NN's processing of the bulk sensor data for generating the at least one output. Improving performance of the at least one NN's processing of the bulk sensor data enables the system to, for example, identify a safety hazard sooner, enabling the autonomous driving to divert the vehicle and avoid contact with the safety hazard.

Aspects disclosed in the detailed description include communicating low-speed and high-speed parallel bit streams over a high-speed serial bus. In one aspect, a data transmitting circuit converts a low-speed parallel bit stream into a high-speed parallel bit stream and then serializes the converted high-speed parallel bit stream based on a high-speed reference frequency. In another aspect, a data receiving circuit recovers the low-speed parallel bit stream from the high-speed parallel bit stream if the low-speed parallel bit stream is determined to exist in the high-speed parallel bit stream. By serializing and deserializing the low-speed parallel bit stream based on the high-speed reference frequency, it is possible to communicate the high-speed parallel bit stream and the low-speed parallel bit stream over the high-speed serial bus without requiring additional serializers and deserializers, thus reducing component costs and implementation complexities in both the transmitting circuit and the receiving circuit.
