WebVEX.256 encoded version: The first source operand is a YMM register. The second source operand can be a YMM register or a 256-bit memory location. The destination operand is a YMM register. Bits (MAXVL-1:256) of the corresponding destination ZMM register are zeroed. VEX.128 encoded version: The first source operand is a XMM register. WebMar 5, 2010 · As XMM registers are lower 128-bit part of YMM registers. In the end they are same registers, however extended to 256bits.
