摘要 |
Method, apparatus, and program means for performing a packed multiply high with round and shift operation. The method of one embodiment comprises receiving a first operand having a first set of L data elements. A second operand having a second set of L data elements is received. L pairs of data elements are multiplied together to generate a set of L products. Each of the L pairs includes a first data element from the first set of L data element and a second data element from a corresponding data element position of the second set of L data elements. Each of the L products are rounded to generate L rounded values. Each of said L rounded values are scaled to generate L scaled values. Each of the L scaled values are truncated for storage at a destination. Each truncated value is to be stored at a data element position corresponding to its pair of data elements. |
