DEVICE TO PREDICT EXCEPTIONAL SITUATION "ACCURACY LOSS" OF "MULTIPLICATION WITH ACCUMULATION" OPERATION UNIT Russian patent published in 2013 - IPC G06F7/483 G06F7/499 G06F7/523 

FIELD: information technologies.

SUBSTANCE: device comprises a subblock of prediction of a sum of fractional parts, a counter of senior zeros of the sum of fractional parts, registers of fractional parts of numbers, input registers of number exponents, a counter of junior zeros of the summand fractional parts, a subblock of calculation of a shift of levelling and prediction of a shift of preliminary normalisation, a comparator of early loss of accuracy, a counter of junior zeros of a sum of fractional parts, a comparator of late loss of accuracy.

EFFECT: accelerated process of performance of a flow of independent commands of multiplication with accumulation with permitted exceptional situation of accuracy loss.
