Transposed tile instructions for matrix accelerator unit

Abstract

An accelerator unit (AU) includes tile registers configured to store matrices associated with a machine-learning model to be implemented. Further, the AU supports a tile read column instruction that reads a column of elements from a matrix stored in the tile registers. When executing a tile read column instruction for a matrix, the AU first determines whether a transposed clone of the matrix is stored in the tile registers. If there is no transposed clone stored the AU generates a transposed clone by performing row read and tile write commands using the matrix. After confirming a transposed clone of the matrix is in the tile registers, the AU reads the rows of the transposed clone corresponding to the column indicated in the tile read column instruction.
