Abstract
In a system including vector registers storing right-hand side data and left-hand side data, first and second matrix staging registers, and a systolic array of processing cells for conducting matrix multiplication operations using the right-hand side data and left-hand side data, one or more processors load the right-hand side data from the vector registers to the first matrix staging register based on an instruction indicating whether to transpose the right-hand side data, load the left-hand side data from the vector registers into the second matrix staging register based on another instruction indicating whether to transpose the left-hand side data, load the right-hand side data from the first matrix staging register into the systolic array, and, in a cycle of the matrix multiplication operation, pass one or more columns of the left-hand side data from the second matrix staging register to a column of the systolic array.
