Abstract
Methods, apparatus, systems and articles of manufacture to perform dot product calculations using sparse vectors are disclosed. An example apparatus includes means for generating a mask vector based on a first logic operation on a difference vector and an inverse of a control vector, the control vector based on a first bitmap of a first sparse vector and a second bitmap of a second sparse vector; means for generating a first product of a third value from the first sparse vector and a fourth value from the second sparse vector, the third value based on (i) the mask vector and (ii) a second sparsity map based on the first sparse vector, the fourth value corresponding to (i) the mask vector and (ii) a second sparsity map corresponding to the second sparse vector; and means for adding the first product to a second product of a previous iteration.
