Methods and systems for executing vectorized pythagorean tuple instructions

A method comprising:

• fetching, using fetch circuitry, an instruction having an opcode, an order, a destination identifier, and N source identifiers, N being equal to the order, and the order being one of two, three, and four;
• decoding, using decode circuitry, the fetched instruction;
• and
• executing, by execution circuitry, to, for each element of the identified destination:
• generate N squares by squaring each corresponding element of the N identified sources;
• and
• generate a sum of the N squares and previous contents of the element.

An apparatus comprising:

• means for fetching an instruction having an opcode, an order, a destination identifier, and N source identifiers, N being equal to the order, and the order being one of two, three, and four;
• means for decoding the fetched instruction;
• and
• means for executing to, for each element of the identified destination:
• generate N squares by squaring each corresponding element of the N identified sources;
• and
• generate a sum of the N squares and previous contents of the element.

A non-transitory computer-readable medium containing instructions that, when execute by a processor, cause the processor to:

• fetch, using fetch circuitry, an instruction having an opcode, an order, a destination identifier, and N source identifiers, N being equal to the order, and the order being one of two, three, and four;
• decode, using decode circuitry, the fetched instruction;
• and
• execute, by execution circuitry, to, for each element of the identified destination:
• generate N squares by squaring each corresponding element of the N identified sources;
• and
• generate a sum of the N squares and previous contents of the element.
