Abstract
A method of an aspect includes receiving an instruction. The instruction indicates a first source of a first packed data including state data elements a, b, e, and ffor a current round (i) of a secure hash algorithm 2 (SHA2) hash algorithm. The instruction indicates a second source of a second packed data. The first packed data has a width in bits that is less than a combined width in bits of eight state data elements a, b, c, d, e, f, g, hof the SHA2 hash algorithm. The method also includes storing a result in a destination indicated by the instruction in response to the instruction. The result includes updated state data elements a, b, e, and fthat have been updated from the corresponding state data elements a, b, e, and fby at least one round of the SHA2 hash algorithm.
