Parallel operations on multiple signed elements in a register

The present invention provides methods, apparatus, and article of manufacture for performing parallel operations on multiple signed elements which have been packed into a binary value, each element being associated with a different set of bits. A signs binary value is obtained which contains the sign bits for each element in the register. The signs binary value is then used to remove and/or restore sign bits to each element in single operations. This enables parallel operations to be performed efficiently on multiple signed elements loaded into a register, without incurring loss of data.
