摘要：

PERFORMING PERMUTATIONS IN SOFTWARE CAN FACILITATE MORE WIDESPREAD USE OF SECURE INFORMATION PROCESSING AND FASTER MULTIMEDIA PROCESSING. BUT CURRENT INSTRUCTION SET ARCHITECTURES, EVEN WHEN AUGMENTED WITH SUBWORD-PARALLEL MULTIMEDIA INSTRUCTIONS, DO NOT PROVIDE EFFICIENT, BIT-LEVEL SOFTWARE PERMUTATIONS. FOUR NEW INSTRUCTIONS EACH OFFER A SOLUTION.
