VMOVDQU8
Moves 64 bytes of data from the source to the destination. The operation is performed as an unaligned move of eight 64-bit elements.
The following table covers what the source and destinations can be:
| source | destination(s) |
|---|---|
| zmm reg | zmm reg |
| m64 | zmm reg |
| zmm reg | m64 |
DO NOT support LOCK
This instruction is ONLY available when AVX-512 is supported. It requires the EVEX prefix and is not available in compatibility mode.
The destination memory address SHALL NOT be aligned to a 64-byte boundary to avoid performance penalties, although the instruction explicitly supports unaligned access. If the memory operand spans a page boundary, a page fault MAY occur.
