Instructions and logic for blend and permute operation sequences

Abstract

A processor includes a core to execute an instruction and logic to determine that the instruction will require strided data converted from source data in memory. The strided data is to include corresponding indexed elements from structures in the source data to be loaded into a same register to be used to execute the instruction. The core also includes logic to load source data into preliminary vector registers. The source data is to be unaligned as resident in the vector registers. The core includes logic to apply blend instructions to contents of the preliminary vector registers to cause corresponding indexed elements from the plurality of structures to be loaded into respective interim vector registers, and to apply further blend instructions to contents of the interim vector registers to cause additional indexed elements from the structures to be loaded into respective source vector registers.
