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.

1. An apparatus to process instructions comprising:
a plurality of packed data registers; and an execution unit coupled with the packed data registers, the execution unit, in response to a multiple element-to-multiple element comparison instruction, which is to indicate a first source packed data that is to include a first plurality of packed data elements, a second source packed data that is to include a second plurality of packed data elements, and a destination storage location, operable to store a packed data result that is to include a plurality of packed result data elements in the destination storage location, each of the result data elements to correspond to a different one of the data elements of the second source packed data, each of the result data elements 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 data element of the second source packed data that corresponds to the result data element, each comparison mask bit to indicate a result of a corresponding comparison.
