SHA256 INSTRUCTION SET FOR MESSAGE SCHEDULING OF SHA256 ALGORITHM

摘要

A processor includes a first execution unit for receiving and executing a first instruction to process a first portion of a secure hash algorithm 256 (SHA256) message scheduling operations, the first instruction storing a set of first message inputs And a second operand associated with a second storage location for storing a set of second message inputs. The processor also includes a second execution unit for receiving and executing a second instruction to process a second portion of the SHA256 message scheduling operations and the second instruction comprises a set of intermediate results of the first portion and a third set of message inputs A third operand associated with a third storage location for storing and a fourth operand associated with a fourth storage location for storing a fourth set of message inputs.
