Abstract
A processing device comprises: operation circuits that operate based on a clock signal supplied from a clock generation circuit; a distribution circuit that branches the clock signal and outputs branched clock signals to the operation circuits; and a detection circuit that compares outputs of the operation circuits and detects an error. At least one of the operation circuits is coupled to the distribution circuit via at least one conversion circuit that converts the clock signal into a clock signal capable of detecting an abnormality in the clock signal when an abnormality occurs in the clock signal.
