Instruction for Performing SIMD affine transformation

A non-transitory machine-readable medium to record functional descriptive material comprising one or more executable instructions that, when executed by a processor on behalf of a thread of a machine, cause the processor to:

• access, by the processor, a source data operand set of elements, a transformation matrix operand, and a translation vector operand;
• perform a Single Instruction Multiple Data (SIMD) affine transformation by applying the transformation matrix operand to each element of the source data operand set, and applying the translation vector operand to each transformed element of the source data operand set;
• and
• store a result of the SIMD affine transformation in a SIMD destination register.

A method comprising:

• decoding, by a processor, a first instruction for a Single Instruction Multiple Data (SIMD) affine transformation, the first instruction specifying a source data operand set, a transformation matrix operand, and a translation vector operand;
• performing, by the processor, a SIMD affine transformation responsive to the decoded first instruction by applying the transformation matrix operand to each element of the source data operand set, and applying the translation vector operand to each transformed element of the source data operand set;
• and
• storing a result of the first instruction in a SIMD destination register.

A processing system comprising:

• a memory to store a first instruction for a SIMD secure hashing algorithm round slice;
• and
• a processor comprising:
• an instruction fetch stage to fetch the first instruction;
• a decode stage to decode a first instruction for a Single Instruction Multiple Data (SIMD) affine transformation, the first instruction specifying a source data operand set, a transformation matrix operand, and a translation vector operand;
• and
• one or more execution units, responsive to the decoded first instruction, to:
• perform a SIMD affine transformation by applying the transformation matrix operand to each element of the source data operand set, and applying the translation vector operand to each transformed element of the source data operand set;
• and
• store a result of the first instruction in a SIMD destination register.
