Multiple data element-to-multiple data element comparison processors, methods, systems, and instructions

摘要

An apparatus includes packed data registers and an execution unit. An instruction is to indicate a first source packed data that is to include a first packed data elements, a second source packed data that is to include a second packed data elements, and a destination storage location. The execution unit, in response to the instruction, is to store a packed data result that is to include packed result data elements in the destination storage location. Each of the result data elements is to correspond to a different one of the data elements of the second source packed data. Each of the result data elements is to include a multiple bit comparison mask that is to include a different comparison mask bit for each different corresponding data element of the first source packed data compared with the corresponding data element of the second source packed data.
