Abstract
A computer-implemented method may include (1) maintaining (a) a filter matrix in a filter cache included in a local memory device (LMD) included in a hardware accelerator, and (b) a plurality of activation matrices corresponding to different rows of an activation volume in an activation cache included in the LMD, (2) for each activation matrix, directing a matrix multiplication unit (MMU) included in the hardware accelerator to execute a matrix multiplication operation (MMU) using the filter matrix and the activation matrix, (3) loading an additional filter matrix into the filter cache, and (4) directing the MMU to execute a plurality of additional MMOs, each additional MMO using one filter matrix included in the filter cache and one activation matrix included in the activation cache, such that the MMU reuses the filter matrix for at least one additional MMO and uses the additional filter matrix for a different additional MMO.
