Publication number: 20230221437Abstract: The present disclosure relates generally to systems and methods for configuring architectures for a sensor, and more particularly for light detection and ranging (hereinafter, “LIDAR”) systems based on ASIC sensor architectures supporting autonomous navigation systems. Effective ASIC sensor architecture can enable an improved correlation between sensor data as well as configurability and responsiveness of the system to its surrounding environment and avoid any unnecessary delay within the decision-making process that may result in a failure of the autonomous driving system. It may be essential to integrated multiple functions within an electronic module and implement the functionality with one or more ASICs.Type: ApplicationFiled: September 19, 2022Publication date: July 13, 2023Inventors: David Hall, Anand Gopalan, Mathew Rekow, Pravin Kumar Venkatesan
