Abstract: This application relates to a method, circuit, and radar for detecting a register. The method for detecting the register includes: performing a signature operation on a first data to obtain a first signature; storing the first data in a data register; performing a signature operation on a second data stored in the data register, to obtain a second signature; and comparing the first signature and the second signature to detect the data register.

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.
