MOVNTDQ
Usage: MOVNTDQ dest,src Modifies flags: None
Moves the double quadword in the 'src' to the 'dest' using a non-temporal hint to prevent caching of the data during the write to memory.
Move Double Quadword Non Temporal
MOVNTDQ m128,xmm ; 66 0F E7 /r [WILLAMETTE,SSE2]
MOVNTDQ moves the double quadword from the XMM source register to the destination memory location, using a non-temporal hint. This store instruction minimizes cache pollution.
The 'src' operand is an XMM register, which is assumed to contain integer data (packed bytes, words, doublewords,or quadwords). The 'dest' operand is a 128-bit memory location.
