## Semantics




                    for (i = 0; i < num_owords; ++i) {
                        dst[i] = *(address+i*16); //16 byte, oword- or dword-aligned
                    }

## Description



    Reads contiguous owords (one oword is 16 byte) from the virtual address
    <address>, and stores the result into <dst>. The execution mask is set
    to "NoMask" (i.e., every element is returned).

- **Properties(ub):** 
 
  - Bit[2..0]: Number of owords to read
 
    - 0b000:  1 oword 
    - 0b001:  2 owords 
    - 0b010:  4 owords 
    - 0b011:  8 owords 
  - Bit[3]: indicates whether the address needs to be oword aligned.
 
    - 0b0:  address must be oword aligned 
    - 0b1:  address can be dword aligned
- **Address(scalar):** The read address in units of bytes. Must have type UQ

- **Dst(raw_operand):** The raw operand of a general variable storing the results of the read
