1. A method of performing integer multiply operations on large integer operands having a first number of bit positions using multi-media instructions that only support parallel multiply operations for small operands having a second number of bit positions, wherein the first number is at least twice as large as the second number, the method comprising: manipulating the large integer operands to position segments of the large integer operands into register positions used as source fields by the multi-media instructions; executing a plurality of multi-media parallel multiply instructions to form a series of partial products; and adding the partial products together to produce an integer result having at least the first number of bit positions.
