MMX Instruction Set
AMD-K6 MMX Enhanced Processor Multimedia Technology
20726D/0—January 2000
Preliminary Information
Functional Illustration of the PACKSSWB Instruction
The following list explains the functional illustration of the PACKSSWB instruction:
I
Bits 63–48 of the source operand (mmreg2/mem64) are packed into bits 63–56 of
the destination operand (mmreg1). The result is not saturated because the 16-bit
positive source operand (007Eh) does not exceed the capacity of a signed 8-bit
destination operand.
Bits 47–32 of the source operand are packed into bits 55–48 of the destination
operand. The result is saturated to the largest possible 8-bit positive number
because the 16-bit positive source operand (7F00h) exceeds the capacity of a
signed 8-bit destination operand.
Bits 31–16 of the source operand are packed into bits 47–40 of the destination
operand. The result is saturated to the largest possible 8-bit negative number
because the 16-bit negative source operand (EF9Dh) exceeds the capacity of a
signed 8-bit destination operand.
Bits 15–0 of the source operand are packed into bits 39–32 of the destination
operand. The result is not saturated because the 16-bit negative source operand
(FF88h) does not exceed the capacity of the 8-bit destination operand.
Bits 63–48 of the destination operand are packed into bits 31–24 of the destination
operand. The result is saturated to the largest possible 8-bit negative number
because the 16-bit negative source operand (FF02h) exceeds the capacity of a
signed 8-bit destination operand.
