Abstract: This application provides a point cloud data sorting circuit, method. The point cloud data sorting circuit includes a sorting module, which contains a row caching unit and a row sorting unit. The row caching unit is configured to obtain and cache original point cloud data to be sorted. The original point cloud data is obtained by scanning the field of view with the LiDAR. Between two rows of original point cloud data obtained in one second scanning period, there are N rows of other original point cloud data obtained in another second scanning period. The row sorting unit is configured to perform coordinate transformation on the original point cloud data to obtain target point cloud data sorted according to pitch angles. This allows the sorting of original point cloud data to be achieved using independent hardware, improving the sorting speed of the original point cloud data.

Abstract: A detection circuit of clock anomaly and method, a clock circuit, a chip, and a radar are provided. The detection circuit of clock anomaly includes: a first clock frequency determining unit, configured to determine a first clock frequency of a received first clock signal; a reference determining unit, configured to determine a reference corresponding to the first clock signal, where the reference is determined based on a second clock signal or a timestamp; and a clock anomaly detection unit, connected to the first clock frequency determining unit and the reference determining unit separately and configured to perform anomaly detection on the first clock signal based on the first clock frequency and the reference. This application can improve reliability of the clock signal, thereby improving personal safety and property safety of a user.
