APPARATUS AND METHOD FOR BROADCASTING FROM A GENERAL PURPOSE REGISTER TO A VECTOR REGISTER

摘要

An apparatus and method are described for broadcasting from a general purpose source register to a destination vector register. For example, a method according to one embodiment includes the following operations: selecting data element position N within the destination vector register to be updated; broadcasting a set of data from the general purpose source register to data element position N within the destination vector register if a mask indicator is set to a first indication; and either copying zeroes to data element position N within the destination vector register or maintaining existing values stored within data element position N within the destination vector register if the mask indicator is set to a second indication.
