Abstract
Distributing multiply-accumulate currents across segment mirrors by providing a circuit including an array of resistive elements, the array including rows and columns and first stage current mirrors, each of the first stage current mirrors being electrically coupled to a segment, wherein the segment comprises a columnar subset of the resistive elements, providing, by the array, a vector of current outputs equal to an analog vector-matrix product between a vector of voltage inputs to the array and a matrix of analog resistive weights within the array, wherein the voltage inputs encode a vector of analog input values, wherein each row of resistive elements corresponds to a specific voltage input, determining a score for each of the rows, determining a ranking of the rows of the array according to the score of each row, and mapping each row to a segment according to the ranking.
