AMD 64-Bit Technology 26568—Rev. 3.02—August 2002 PUNPCKLBW Unpack and Interleave Low Bytes Unpacks the low-order bytes from the first and second source operands and packs them into interleaved-byte words in the destination (first source). The high-order bytes of the source operands are ignored. The first source/destination operand is an XMM register and the second source operand is another XMM register or 128-bit memory location. Mnemonic Opcode Description PUNPCKLBW xmm1, xmm2/mem128 66 0F 60 /r Unpacks the eight low-order bytes in an XMM register and another XMM register or 128-bit memory location and packs them into interleaved bytes in the destination XMM register. xmm1 127 64 63 0 xmm2/mem128 127 64 63 0 . . . . . . copy copy copy . . . . . . copy . . . . . . . . . . . . 127 64 63 0 punpcklbw-128.eps If the second source operand is all 0s, the destination contains the bytes from the first source operand zero-extended to 16 bits. This operation is useful for expanding unsigned 8-bit values to unsigned 16-bit operands for subsequent processing that requires higher precision.
