SYSTEMS, APPARATUSES, AND METHODS FOR GENERATING AN INDEX BY SORT ORDER AND REORDERING ELEMENTS BASED ON SORT ORDER

Disclosed embodiments relate to apparatuses, systems, and methods for performing sort indexing and/or permutation using an index. An exemplary apparatus or processor comprises: decode circuitry to decode an instruction, the instruction to include a first field to identify a location of a source vector, a second field to identify a location of a destination vector, and an opcode to indicate to execution circuitry to execute the decoded instruction to index values of the source vector and store a result of the indexing in the destination vector by generating, per each element of the source vector, an index value using one or more comparisons; and execution circuitry to execute the decoded instruction as indicated by the opcode.
