Title:
INFORMATION PROCESSING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/029766
Kind Code:
A1
Abstract:
An information processing circuit has a calculation circuit that receives an input signal and a checking circuit that receives the input signal, wherein the calculation circuit outputs a numerical solution calculated on the basis of the input signal to the checking circuit, and the checking circuit restores the numerical solution received from the calculation circuit to a restored input signal, determines whether an error exists or not on the basis of the restored input signal restored and the received input signal, and outputs a determination result that shows existence/nonexistence of the error, with the result that it is possible to perform error detection with less circuit amount as compared to the case of doubling the circuit.
