Abstract:
Instructions and logic provide for a Single Instruction Multiple Data (SIMD) SM4 round slice operation. Embodiments of an instruction specify a first and a second source data operand set, and substitution function indicators, e.g. in an immediate operand. Embodiments of a processor may include encryption units, responsive to the first instruction, to: perform a slice of SM4-round exchanges on a portion of the first source data operand set with a corresponding keys from the second source data operand set in response to a substitution function indicator that indicates a first substitution function, perform a slice of SM4 key generations using another portion of the first source data operand set with corresponding constants from the second source data operand set in response to a substitution function indicator that indicates a second substitution function, and store a set of result elements of the first instruction in a SIMD destination register.

Claim (Index 38):
A processor comprising:\n a cache to store an instruction, the instruction to identify one or more source operands that are to have source data for one or more SM4 cipher rounds and source data for one or more SM4 key expansion rounds; and a circuit to perform the instruction, and store a result of the instruction in a single destination register, the result to include:\n one or more results for the one or more SM4 cipher rounds; and \n one or more results for the one or more SM4 key expansion rounds.
