Methods for multiplying matrices using a plurality of chiplets

A plurality of chiplets may be used to multiply two matrices A and B. Matrix A may be decomposed into horizontal stripes and matrix B may be decomposed into vertical stripes. Each of the horizontal stripes may be multiplied by each of the vertical stripes to form the output matrix C. Specifically, horizontal stripes may be stored in a stationary, distributed manner across the chiplets, while the vertical stripes (or sub-vertical stripes) may be passed between respective pairs of the chiplets until each of the vertical stripes (or sub-vertical stripes) of matrix B has been received and processed by each of the chiplets. The vertical stripes may be passed along one or more paths that interconnect the chiplets. Similar techniques can be applied to an arrangement in which the vertical stripes are stationary and the horizontal stripes (or sub-horizontal stripes) are passed between respective pairs of the chiplets.
