Abstract
There is disclosed an arithmetic unit which allows a combined multiply-add operation to be carried out in response to execution of a single computer instruction. This is particularly useful in a packed arithmetic environment, when a operand comprises a plurality of packed objects and the intention is to carry out the same arithmetic operation on respective pairs of objects in different operands. There is also provided a computer and a method of operating a computer to effect the combined multiply-add operation.
