Abstract
A special-purpose hardware accelerator may include a cache configured to store an input matrix related to performing a convolution operation and a matrix-multiplication subsystem pre-configured with matrix-transform coefficients for performing matrix-transform operations. The matrix-multiplication subsystem may perform the convolution operation by (1) reading the input matrix from the cache, (2) transforming the input matrix via matrix multiplication, (3) transforming, via matrix multiplication, a parameter matrix that includes convolution parameters for performing the convolution operation, (4) applying the transformed parameter matrix to the transformed input matrix via an element-wise multiplication operation, and then (5) performing an inverse-transformation operation on the results of the element-wise multiplication operation to create an output matrix for the convolution operation. Various other systems and methods are also disclosed.
