MMX Instruction Set
AMD-K6 MMX Enhanced Processor Multimedia Technology
20726D/0—January 2000
Preliminary Information
Functional Illustration of the PACKSSDW Instruction
The following list explains the functional illustration of the PACKSSDW instruction:
I
Bits 63–32 of the source operand (mmreg2/mem64) are packed into bits 63–48 of
the destination operand (mmreg1). The result is saturated to the largest possible
16-bit negative number because the 32-bit negative source operand (8000_0002h)
exceeds the capacity of the signed 16-bit destination operand.
Bits 31–0 of the source operand are packed into bits 47–32 of the destination
operand. The result is saturated to the largest possible 16-bit positive number
because the 32-bit positive source operand (0000_8000h) exceeds the capacity of
the 16-bit destination operand.
Bits 63–32 of the destination operand are packed into bits 31–16 of the destination
operand. The results are not saturated because the 32-bit negative source operand
(FFFF_8002h) does not exceed the capacity of the 16-bit destination operand.
Bits 31–0 of the destination operand are packed into bits 15–0 of the destination
operand. The results are not saturated because the 32-bit positive source operand
(0000_01FCh) does not exceed the capacity of the 16-bit destination operand.
