US Patent 10884836 Arithmetic processing device and method therefor

An arithmetic processing device according to an embodiment performs actual arithmetic processing for data inputted periodically and determination whether or not an error occurs in the actual arithmetic processing in real time. An ISP of this device includes an arithmetic processing circuit for performing image arithmetic processing for image data in moving image inputted from imaging device at each of frames, and a diagnostics control circuit and diagnostics processing circuit connected to the arithmetic processing circuit. The ISP, with these components, performs the image arithmetic processing for the image data in the moving image at each of the frames and error detection in the image arithmetic processing in real time.
