Expand description

Select a single value in a to store at some position in b, Then zero elements according to IMM8.

IMM8 specifies which bits from operand a will be copied, which bits in the result they will be copied to, and which bits in the result will be cleared. The following assignments are made:

  • Bits [7:6] specify the bits to copy from operand a:

    • 00: Selects bits [31:0] from operand a.
    • 01: Selects bits [63:32] from operand a.
    • 10: Selects bits [95:64] from operand a.
    • 11: Selects bits [127:96] from operand a.
  • Bits [5:4] specify the bits in the result to which the selected bits from operand a are copied:

    • 00: Copies the selected bits from a to result bits [31:0].
    • 01: Copies the selected bits from a to result bits [63:32].
    • 10: Copies the selected bits from a to result bits [95:64].
    • 11: Copies the selected bits from a to result bits [127:96].
  • Bits [3:0]: If any of these bits are set, the corresponding result element is cleared.
