Some embodiments include a processor comprising: a decoder to decode instructions for a SIMD SM3 message expansion, specifying first and second source data operand sets, and an expansion extent. Processor execution units, responsive to the instruction, perform a number of SM3 message expansions, from the first and second source data operand sets, determined by the specified expansion extent and store the result into a SIMD destination register. Some embodiments also execute instructions for a SIMD SM3 hash round-slice portion of the hashing algorithm, from an intermediate hash value input, a source data set, and a round constant set. Processor execution units perform a set of SM3 hashing round iterations upon the source data set, applying the intermediate hash value input and the round constant set, and store a new hash value result in a SIMD destination register."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Instructions and logic to provide SIMD SM3 cryptographic hashing functionality","description":"Instructions and logic provide SIMD SM3 cryptographic hashing functionality.
