AMD-K6 MMX Enhanced Processor Multimedia Technology
Preliminary Information
Functional Illustration of the PUNPCKLDQ Instruction
In the following figure, the destination register is shown at the center to illustrate the
flow of data from the two source operands.
In the functional illustration of the PUNPCKLDQ instruction, the 32-bit value from
mmreg1 is stored in the low-order 32 bits of the 64-bit result. The mmreg2/mem32
source operand is set to all zero bits so it can provide zero fill in the high-order 32 bits
of the 64-bit result. This is a method that can be used to expand unsigned 32-bit values
into unsigned 64-bit operands for subsequent processing that requires higher
precision.
