Abstract: A system and method of accelerating execution of a NN model, by at least one processor may include: receiving a first matrix A, representing elements of a kernel K of the NN model and a second matrix B, representing elements of an input I to kernel K; producing from matrix A, a group-sparse matrix A?, comprising G tensors of elements. The number of elements in each tensor is defined by, or equal to a number of entries in each index of an input tensor register used for a specific Single Instruction Multiple Data (SIMD) tensor operation, and all elements of A? outside said G tensors are null. The system and method may further include executing kernel K on input I, by performing at least one computation of the SIMD tensor operation, having as operands elements of a tensor of the G tensors and corresponding elements of the B matrix.

Abstract: A computer processor may include a number of cores, a shared cache shared among the cores, and a local cache associated with each core and used by that core only. Input data for a neural network (NN) layer may be partitioned into a set of tiles of size T×T, and the tile set may be partitioned into blocks of R tiles. For each block, a core may perform a transform operation on the tiles to produce transformed data matrices fitting in a local cache, and a set of multiply operations, each multiply operation using a transformed data matrix and a transformed kernel matrix from a set of transformed kernel matrices. The set of transformed kernel matrices may fit in the shared cache. The result of at least one of the multiply operations may be stored in a location used to store a transformed data matrix.
