Sparse convolution of multiple vectors in a digital signal processor

摘要

A method for performing convolution on one or more first vectors including multiple vector elements using one or more second vectors. The method includes identifying one or more of the multiple vector elements of the one or more first vectors that do not have a value of zero, and convoluting the one or more first vectors with the one or more second vectors for the identified one or more of the multiple vector elements of the one or more first vectors that do not have a value of zero.
