摘要:
An apparatus and method are described for permuting data elements with masking. For example, a method according to one embodiment includes the following operations: reading values from a mask data structure to determine whether masking is implemented for each data element of a destination operand; if masking not implemented for a particular data element, then selecting data elements from the destination operand and a second source operand based on index values stored in a first source operand to be copied to data element positions within the destination operand, wherein any one of the data elements from either the destination operand and the second source operand may be copied to any one of the data element positions within the destination operand; if masking is implemented for a particular data element of the destination operand, then performing a designated masking operation with respect to that particular data element.
