ABSTRACT:
A processor including general-purpose and cryptographic functionality, in which cryptographic operations are visible to user-specified software. According to one embodiment, a processor may include instruction execution logic configured to execute instructions specified by a user of the processor, where the instructions are compliant with a general-purpose instruction set architecture. The processor may further include a cryptographic functional unit configured to implement a plurality of cryptographic operations, and further configured to process the cryptographic operations independently of the instruction execution logic. A subset of the instructions may be executable to cause individual ones of the cryptographic operations to be processed by the cryptographic functional unit.
