----------O-EMMS-----------------------------------
OPCODE EMMS	-  Empty MMX State

CPU:  all which supported IA MMX:
      Pentium (P55C only), Pentium (tm) Pro  (P6) future models
Type of Instruction: User

Instruction: EMMS

Description:

	FloatPointTagWord  <-  FFFFh

Note:	  The EMMS instruction sets the values of the floating-point (FP) tag
	word to empty (all ones). EMMS marks the registers as available, so
	they can subsequently be used by floating-point instructions.
	  If a floating-point instruction loads into one of the registers
	before it has been reset by the EMMS instruction, a floating-point
	stack overflow can occur, which results in a FP exception or incorrect
	result. All other MMX instructions validate the entire FP tag word (all
	zeros).
	  This instruction must be used to dear the MMX state at the end of all
	MMX routines, and before calling other routines that may execute
	floating-point instructions.

Flags affected:	 None

Instruction: PADDUSW  dest,src

Description:

	dest[63..48]	<-   SaturateToUnsignedWord(dest[63..48] + src[63..48])

Note:	  This instruction adds the unsigned words of the source to the
	unsigned words of the destination operand and writes the results to the
	MMX register.
	  When the result is larger than the range of an unsigned word
	(overflow), the value is saturated to FFFFH. When the result is smaller
	than the range of an unsigned byte (underflow), the value is saturated
	to 0000H.

Notes:		The PMACHRIW multiplies the two source operands using the
	method described for PMULHRW, and then accumulates the result with
	the value in the implied destination register using wrap-around
	arithmetic. The final result is placed in the implied DEST register.
		The DEST must be an MMX register. The SRC must be a 64-bit
	memory operand. The destination operand is an implied MMX register
	that depends on the DEST.

Pentium (tm) is superscalar microprocessor
i.e. it may execute >1 instruction per CLK
cycle. It may execute maximum 2 instruction
per cycle.It have two integer pipes to execute
instruction. This pipes not same, and some
instruction may pairing (i.e. execute together)
(only if not link with this 2 instruction)
only in U pipe, some other only in V pipe, other
in any pipe,other absolutely not pairing and they
executed on U pipe only.

APPENDIX G

BUGS & CPU IDENTIFICATION INFO

1) How to separate i386SX and i386DX
   (Cx486SLC and Cx486DLC)
   Note:  With 386DX type CPU possible to used
	  287 class NPX, and bit 4 in CR0
	  ET - Extention Type on DX we may to
	  clear to 0, but for SX and REAL 486
	  this bit always 1.
   Routine:
	mov	eax,cr0
	push	eax
	and	al,0efh
	mov	cr0,eax
	mov	eax,cr0
	test	al,10h
	pop	eax
	mov	cr0,eax
	jne	SX/SLC
	jmp	DX/DLC

2) How to separate i486SX and i487SX/i486DX/DX2 etc
	Routine:
memory_location	DW	?
	mov	memory_location,0
	fninit
	fstcw	memory_location
	cmp	memory_location,037Fh
	jz	i486SX
	jmp	i486DX/DX2etc/i487SX

3) How to separate Cyrix's CPUs and other
       Be sure that Your CPU no Pentium before
       UMOV executed on Intel and other in
       Non SM modes as MOV.
       But Cyrix executed this instruction as
       Double NOP, and never generate INT 6.
       So.
Mem_Loc	DW  1
	xor	ax,ax
	umov	ax,Mem_Loc
	or	ax,ax
	jz	Cyrix
	jmp	No_Cyrix

4) Standart Way: Part 1
   (Intel recomended this way)

	pushf
	pop	ax
	and	ax,0fffh	; Clear bits 15..12
	push	ax
	popf
	pushf
	pop	ax
	and	ax,0f000h	; Is bits 15..12=0 ?
	jz	286_CPU
	and	ax,8000h	; Is bit 15=0
	jz	386_and_Higher
	jmp	86_88and186_186etc

5) How separate 86/88, 186/188 and NECs

	mov	ax,1
	mov	cl,33
	shl	ax,cl
	jnz	186_188
	pusha		; Executed on 8086/8088 as JMP $+2
	stc
	jc	NECs
	jmp	86_88

6) Non CMOS 8086/88 execute command MOV CS,xxxx (Opcode 8Eh ...)
   CMOS 80C86/88 ignore it.

7) Then Invalid Opcode NEC/Sony V40/V50 do INT 6
		       NEC/Sony V20/V30 don't.

8) Remember POP CS instruction on non-CMOS 8086/8088.

9) PUSH SP
   286 placed in stack new value of SP
   86/88 old.

10) Best way to Reset 286+ in Real Mode:
    mov	  sp,1		(LOW BOUND)
    push  smth

    note:
	 mov sp,ffffh	(HIGH BOUND)
	 pop smth
	caused non Stack Fault, but GPF.

11) Maximal Length of Instructian
    86: N/R
    286:  10 byte
    386+: 15 byte

12) UMC Chips Detection (UMC U486SX, for other use CPUID)
    db	64h,0dbh	; look like "SETALC FS:", but it none
    cmp eax,0ab6b1b07h
    je	u486SX
    jne Other

13) MSW on 386/486
    On 386 MSR reserved bits = 1, so Real Mode 386  usually MSW = FFF0
				     Real Mode 486+ usually MSW = 0010
    smsw ax
    and	 ah,ah
    jnz	 cpu_386
    jz	 cpu_486_and_more

14) Selectors PUSH
    486 write 2 bytes to stack and ADD ESP,4
    Pentium Write all 4 bytes (and two of it are zero)
    (The same situation, then pushing 16-bit error code on exception)

15)  TSS I/O Map Addressing
     Then I/O Map Base Address in TSS contain for example FFFFh,
     (don't forget TSS Limit)
     i486 wrap around segment and access invalid address near start of TSS.
     Pentium caused GPF.

16)  Prefetcher
     up to 486 and 486 then instruction fetched to prefetcher and we write
     into memory area, where this instruction placed, will be execute
     already-prefetched command, but non-new.
     Pentium flush prefetcher, when detect modify of fetched cache line,
     so, for avoid this flush use different linear addresses for modify.

      CPU	Size_of_prefetch_queue		Number_of_empty_bytes_in
		    (bytes)			queue_needed_for_initiate
						prefetch_cycle
    8086/186/V20	6			     2
    8088/188/V30	4			     1
    286			6			     2
    386SX		16			     2
    386DX		16			     4

17)   DR4/DR5 :))
      on 486 then accessing DR4/DR5  CPU accessed DR6/DR7.
      on Pentium if CR4.DE=0 the same situation as on 486,
      but if CR4.DE=1 then MOV from/to DR4/DR5 caused GPF.

18)   NexGen Nx586
      On Pentium and 486 we cannot set ET flag in CR0.
      We may set ET flag in CR0.
      (On 386 we may set this flag too).

19)   IDIV
      if result of IDIV will be 80h (byte IDIV) or 8000h (word IDIV)
      86/88 caused INT 0 - Division by zero,
      on 286+ 80h/8000h keeps as result and no exception

20)   Division by zero
      On 86/88 pointer in stack then caused Division by zero
      pointed to DIV/IDIV instruction,
      on 286+ pointed to next instruction.

21)   FPU Exception
      So, then FPU command with prefixes caused exception
      on 86/88 pointer to failed instruction on stack pointed to ESC command,
      on 386+ pointed to one of prefixes before ESC.

22)   String commands
      if while 86/88 execute string instruction interrupt caused,
      CPU end execute instruction and goto next instruction,
      CX,SI and DI have values after last complete iteration
      To avoid it, use:
	pushf
	cli
	rep STRING
	popf

23)   How to separate C&T 386 CPU form other (AMD,Intel)
	(C&T none have POPAD bug, but Intel and AMD have)
	mov	esi,32
	mov	eax,12345678h
loop:
	mov	ebx,eax
	mov	edx,0
	mov	esi,0
	pushad
	popad
	mov	ecx,[edx+edi]
	cmp	eax,ebx
	jnz	AMD_Intel
	rol	eax,1
	dec	esi
	jnz	loop
	jmp	C_T_CPUs

APPENDIX R    UNDEFINED FLAGS

See CPUUTIL.ZIP for UFLAGS.COM !!

Hey, Guys!  Do You really think about set of 80x86 CPU cores and
"That's mean UNDEFINED FLAGS?".

1) Do You Ask Yourself: "How many 80x86 base cores are?"
   Let's discuss about definitions:
     What's mean "base core"?
     "Base core" mean: same core clock for instructions, same undefined
     features e.t.c., and was produced many CPUs this type.
     (so, i486DX2 and i486DX have same core),
     (but i486DX2 and IntelDX4 have differ (cos MUL time +etc.).
     (i486SX integer core is look like i486DX core without NPX and all things
      joined with it).

    So we have next list of Main Base Cores:
	8086/8088		(186s skipped)
	286
	386			(have some differents on vendors)
	Cx486SLC/Cx486DX	(and all clones like TI486SXL)
	i486
	UMC U5S
	Cyrix Cx5x86 (M1sc)
	Pentium
	NexGen Nx5x86
	Cyrix Cx6x86 (M1)
	AMD Am5k86
	Pentium Pro

    Of course  one Main Base Core have many CPUs which have differents between
    self, for example: TI486SXL have Cx486DLC Base Core.

    This Base Cores is relative, of course.
    (We may discuss Where to push C&T 38600DX etc., but it doesn't matter)

2) How many situation with Undefined Flags exists?

	Not too many, as You think:
		MUL
		DIV
		IMUL
		IDIV
		NEG	(ZF)
		AND/OR/XOR/etc (AF)
		Shift/Rotates (OF)
	and  some more.

3) What's To Do?

Let's make next experiment:

	AH = 0
	AH -> FLG
	PERFORM TEST SEQUENCE
	FLG -> AH
	GET RESULT # 1
	AH = FF
	AH -> FLG
	PERFORM TEST SEQUENCE
	FLG -> AH
	GET RESULT # 2
	ANALYSING RESULTS. (WHICH BIT PASSED, WHICH DRIVEN BY INSTRUCTION

Main Test Sequences are:

MUL:	mov	ax,0000h
	mov	bx,1234h
	mul	bx

DIV:	mov	ax,1234h
	mov	bl,22h
	div	bl

IMUL:	mov	ax,0092h
	mov	bl,22h
	imul	bl

IDIV:	mov	ax,0ffeeh
	mov	bl,22h
