摘要：
Embodiments of systems, apparatuses, and methods for performing an expand and/or compress instruction in a computer processor are described. In some embodiments, the execution of an expand instruction causes the selection of elements from a source that are to be sparsely stored in a destination based on values of the writemask and store each selected data element of the source as a sparse data element into a destination location, wherein the destination locations correspond to each writemask bit position that indicates that the corresponding data element of the source is to be stored.
