SHUFFLE PATTERN GENERATING CIRCUIT, PROCESSOR, SHUFFLE PATTERN GENERATING METHOD, AND INSTRUCTION

摘要

A shift duplicating unit carries out a one-bit left bit shift of individual indexes on the basis of an index line (702) of four (bit width of eight bits) indexes that have been inputted, and outputs an index line (902) obtained by making two-by-two duplicates of each index. An adder then outputs a shuffle pattern (703) obtained by adding the values of 1, 0, 1, 0, 1, 0, 1, 0 in order from the left end to the index line (902).
