Abstract
A method of multiplying and accumulating two sets of values in a computer system. A packed multiply add is performed on a first portion of a first set of values packed into a first source and a first portion of a second set of values packed into a second source to generate a first result. The first result is unpacked into a plurality of values (e.g. two). The plurality of values is then added together to form a resulting accumulation value.
