A method and system for residual calibration of an optical multiplier accumulator

Abstract

The present application belongs to the field of information technology, and particularly relates to a residual error calibration method and system for an optical multiplier. The present application provides a residual error calibration method and system for an optical multiplier, and the present application is used for error compensation of the optical multiplier, can reduce the equivalent matrix deviation of the optical multiplier caused by non-ideal factors such as process error, limited configuration voltage precision, and realizes the effect of improving the calculation precision of the optical multiplier and the accuracy of applications such as picture pattern recognition. The present application has the beneficial effects that: (1) a compensation method and system for the optical multiplier are provided, and the effect of improving the matrix multiplication calculation precision and the accuracy of applications such as pattern recognition can be realized; (2) the compensation effect can be controlled by setting an arbitrary compensation number.
