Mac operator related to correcting a computational error

Abstract

A multiplication and accumulation (MAC) operator includes a data input circuit configured to receive first operands and second operands and configured to output the first operands and third operands, a multiplication circuit configured to generate multiplication data by performing a multiplication operation on the first operands and the third operands, an addition circuit configured to generate multiplication addition data by performing an addition operation on the multiplication data, an accumulating circuit configured to generate accumulative data by performing an accumulative addition operation on the multiplication addition data and feedback data, and an error correction circuit configured to detect a computational error in the accumulative data when a computational error occurs, and configured to output, as MAC result data, accumulative data having the computational error corrected.
