Document Type and Number:
Japanese Patent JP2022184410
Kind Code:
A
Abstract:
To provide an arithmetic device capable of achieving streamlining while accurately comparing a plurality of system processes.SOLUTION: An arithmetic device comprises a plurality of system circuits and a comparator. Each of the plurality of system circuits includes an input unit which receives input data, and a processing unit which performs signal processing for the input data from the input unit. The comparator compares whether processes of the processing units in respective system circuits match with each other. When a process of the processing unit in any of the system circuits is delayed, the comparator matches a process timing of the processing units of respective systems by delaying processes of the processing units of other systems.SELECTED DRAWING: Figure 4
