3DNow! Technology Manual
21928G/0—March 2000
The rules for exceptions are the same for both MMX and
3DNow! instructions. In addition, exception detection and
handling is identical for MMX and 3DNow! instructions. None
of the exception handlers need modification.
Notes:
1. An invalid opcode exception (interrupt 6) occurs if a
3DNow! instruction is executed on a processor that does
not support 3DNow! instructions.
2. If a floating-point exception is pending and the processor
encounters a 3DNow! instruction, FERR# is asserted and,
if CR0.NE = 1, an interrupt 16 is generated. (This is the
same for MMX instructions.)
Prefixes
The following prefixes can be used with 3DNow! instructions:
I
The segment override prefixes (2Eh/CS, 36h/SS, 3Eh/DS,
26h/ES, 64h/FS, and 65h/GS) affect 3DNow! instructions
that contain a memory operand.
The address-size override prefix (67h) affects 3DNow!
instructions that contain a memory operand.
The operand-size override prefix (66h) is ignored.
The LOCK prefix (F0h) triggers an invalid opcode exception
(interrupt 6).
The REP prefixes (F3h/ REP/ REPE/ REPZ, F2h/ REPNE/
REPNZ) are ignored.
