## Opcode
SVM = 0x4e
BLOCK_LD = 0x01
## Format
| | | |
| --- | --- | --- |
| 0x4e(SVM) | 0x01(BLOCK_LD) | Properties | Address | Dst |
## 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
