US Patent 8984043 Multiplying and adding matrices

An apparatus and method are described for multiplying and adding matrices. For example, one embodiment of a method comprises decoding by a decoder in a processor device, a single instruction specifying an m-by-m matrix operation for a set of vectors, wherein each vector represents an m-by-m matrix of data elements and m is greater than one; issuing the single instruction for execution by an execution unit in the processor device; and responsive to the execution of the single instruction, generating a resultant vector, wherein the resultant vector represents an m-by-m matrix of data elements.
