Abstract
Techniques for instruction prefix encoding for cryptographic computing capability data types are described. In an embodiment, an apparatus includes an instruction decoder to decode a first instruction including a first prefix; and cryptography circuitry to perform a cryptographic operation on data, the cryptographic operation to be based at least in part on the first prefix and a relative enumeration in a pointer to the data.
Claims20
A processor device comprising:
- an instruction decoder to decode a first instruction including a first prefix;
- and
- cryptography circuitry to perform a cryptographic operation on data, the cryptographic operation to be based at least in part on the first prefix and a relative enumeration in a pointer to the data.
A method comprising:
- decoding, by an instruction decoder of a processing device, a first instruction including a first prefix;
- and
- performing, by cryptography circuitry of the processing device, a cryptographic operation on data, the cryptographic operation to be based at least in part on the first prefix and a relative enumeration in a pointer to the data.
A non-transitory machine-readable medium storing at least a single instruction which, when executed by a machine, causes the machine to perform a method comprising:
- decoding, by an instruction decoder of a processing device, a first instruction including a first prefix;
- and
- performing, by cryptography circuitry of the processing device, a cryptographic operation on data, the cryptographic operation to be based at least in part on the first prefix and a relative enumeration in a pointer to the data.
