MULTIPLICATION AND ACCUMULATION (MAC) OPERATOR AND PROCESSING-IN-MEMORY (PIM) DEVICE INCLUDING THE MAC OPERATOR

摘要

A multiplying-and-accumulating (MAC) operator for performing a MAC arithmetic operation of a weight matrix employing “M×N”-number of weight sub-matrixes as elements and a vector matrix employing “N”-number of vector sub-matrixes as elements (where “M” and “N” are natural numbers which are equal to or greater than two). The “M×N”-number of weight sub-matrixes are located at cross points of first to Mth weight matrix group rows and first to Nth weight matrix group columns, respectively. The “N”-number of vector sub-matrixes are located at cross points of first to Nth vector matrix group rows and one vector matrix group column, respectively. The MAC operator is configured to perform the MAC arithmetic operations of a matrix group column unit for the “M”-number of weight sub-matrixes arrayed in each of the first to Nth weight matrix group columns and the vector sub-matrix arrayed in each of the Nth vector matrix group rows.
