Single precision vector permute immediate with "word" vector write mask

The present invention is generally related to the field of image processing, and more specifically to an instruction set for processing images. Vector processing may involve performing a plurality of permute operations to arrange vector operands in desired locations of a register prior to performing vector operation, for example, a cross product. The permute instructions may be dependent on one another and may require the use of temporary registers. Embodiments of the invention provide a permute instruction wherein a mask field may be used to specify a particular location of a target register in which to transfer data, thereby reducing the number of instructions for arranging data, reducing dependencies between instructions, and the usage of temporary registers.
