    • According to one embodiment, a processor includes an instruction decoder to receive a first instruction to perform first SKEIN256 MIX-PERMUTE operations, the first instruction having a first operand associated with a first storage location to store a plurality of odd words, a second operand associated with a second storage location to store a plurality of even words, and a third operand. The processor further includes a first execution unit coupled to the instruction decoder, in response to the first instruction, to perform multiple rounds of the first SKEIN256 MIX-PERMUTE operations based on the odd words and even words using a first rotate value obtained from a third storage location indicated by the third operand, and to store new odd words in the first storage location indicated by the first operand.
    • 根据一个实施例,处理器包括指令解码器,用于接收执行第一SKEIN256 MIX-PERMUTE操作的第一指令,所述第一指令具有与第一存储位置相关联的第一操作数,以存储多个奇数字,第二操作数相关联 具有存储多个偶数字的第二存储位置和第三操作数。 处理器还包括响应于第一指令而耦合到指令解码器的第一执行单元,使用从第三指令获得的第一旋转值,基于奇数字和偶数字进行第一SKEIN256 MIX-PERMUTE操作的多轮 由第三操作数指示的存储位置,并将新的奇数字存储在由第一操作数指示的第一存储位置中。
