Description INSTRUCTION SET REFERENCE Shifts the bits in the individual data elements (words, doublewords, or quadword) in the first source operand to the right by the number of bits specified in the count operand. As the bits in the data elements are shifted right, the empty high-order bits are filled with the initial value of the sign bit of the data. If the value specified by the count operand is greater than 15 (for words), or 31 (for doublewords), then the destination operand is filled with the initial value of the sign bit. Note that only the first 64-bits of a 128-bit count operand are checked to compute the count. If the second source operand is a memory address, 128 bits are loaded. The (V)PSRAW instruction shifts each of the words in the first source operand to the right by the number of bits specified in the count operand; the (V)PSRAD instruction shifts each of the doublewords in the first source operand. Legacy SSE instructions: In 64-bit mode using a REX prefix in the form of REX.R permits this instruction to access additional registers (XMM8-XMM15). 128-bit Legacy SSE version: The destination and first source operands are XMM registers. Bits (255:128) of the corresponding YMM destination register remain unchanged. The count operand can be either an XMM register or a 128-bit memory location or an 8-bit immediate. VEX.128 encoded version: The destination and first source operands are XMM registers. Bits (255:128) of the corresponding YMM destination register are zeroed. The count operand can be either an XMM register or a 128-bit memory location or an 8-bit immediate. VEX.256 encoded version: The destination and first source operands are YMM registers. The count operand can be either an XMM register or a 128-bit memory location or an 8-bit immediate.
