摘要：
A processor includes an instruction decoder to receive a first instruction to process a SHA-1 hash algorithm, the first instruction having a first operand to store a SHA-1 state, a second operand to store a plurality of messages, and a third operand to specify a hash function, and an execution unit coupled to the instruction decoder to perform a plurality of rounds of the SHA-1 hash algorithm on the SHA-1 state specified in the first operand and the plurality of messages specified in the second operand, using the hash function specified in the third operand.
