<p>Note: VEX.vvvv and EVEX.vvvv is reserved and must be 1111b otherwise instructions will #UD.</p>
|
|||
|
|
<p>EVEX.512 encoded version:</p>
|
|||
|
|
<p>Moves 512 bits of packed single precision floating-point values from the source operand (second operand) to the destination operand (first operand). This instruction can be used to load a ZMM register from a 512-bit float32 memory location, to store the contents of a ZMM register into memory. The destination operand is updated according to the writemask.</p>
|
|||
|
|
<p>VEX.256 and EVEX.256 encoded versions:</p>
|
|||
|
|
<p>Moves 256 bits of packed single precision floating-point values from the source operand (second operand) to the destination operand (first operand). This instruction can be used to load a YMM register from a 256-bit memory location, to store the contents of a YMM register into a 256-bit memory location, or to move data between two YMM registers. Bits (MAXVL-1:256) of the destination register are zeroed.</p>
|
|||
|
|
<p>128-bit versions:</p>
|
|||
|
|
<p>Moves 128 bits of packed single precision floating-point values from the source operand (second operand) to the destination operand (first operand). This instruction can be used to load an XMM register from a 128-bit memory location, to store the contents of an XMM register into a 128-bit memory location, or to move data between two XMM registers.</p>
|
|||
|
|
<p>128-bit Legacy SSE version: Bits (MAXVL-1:128) of the corresponding destination register remain unchanged.</p>
|
|||
|
|
<p>When the source or destination operand is a memory operand, the operand may be unaligned without causing a general-protection exception (#GP) to be generated.</p>
|
|||
|
|
<p>VEX.128 and EVEX.128 encoded versions: Bits (MAXVL-1:128) of the destination register are zeroed.</p>
