1. A processor comprising:

  • a decode stage to decode a first instruction for a Single Instruction Multiple Data (SIMD) binary finite field multiplicative inverse, the first instruction specifying a source data operand set, and a monic irreducible polynomial; and

    one or more execution units, responsive to the decoded first instruction, to;

    compute a SIMD binary finite-field multiplicative inverse modulo the irreducible polynomial for each element of the source data operand set; and

    store a result of the first instruction in a SIMD destination register.
