   *** Amithlon x86 Native Memory Copy Routines ***
   ***              (c) 2002 RaM                ***
   ================================================


USAGE:

	Just run from CLI, ensure 16k stack min.

	QUIET	-	no output
	MMX	-	Dont use K7/Athlon Extensions
	STD	-	Dont use K7 or 3D Now!


	FOR PIII CPU:	Use only STD, others will crash

	FOR K7:		Use as is (no args full opt)
	
	FOR Others:	K6 try MMX, others try STD



Comparisons made using custom tool MemTest with
multitasking disabled and a minimal boot.

No	  -	No patch applied, just std calls,
		interesting to note how the JIT
		really comes into play.

CMQ060	  -	CopyMemQuicker 060 from Aminet.
		Originally Busse(?), this version
		was 1.5b from Sintonen.

Fastx86	  -	FastCopy (FastCopy.elf / FastCopy_x86)
		as supplied in the extras/ drawer
		on the Amithlon CD

RaMithlon -     My own x86 Athlon optimized patch.

NOTE NOTE -> Dont run before you have initialized a
Picasso screen (i.e. AFTER iprefs in startup) as the
x86 ASM code is making the native screen hack go funny
while a copy is in progress. Probably doesn't like
fastcalling the x86 at that stage.

RaMithlon.elf must be residing in some dir as the
RaMithlon Amiga executable.



HISTORY
-------

1.1	FIXED PIII problems - 3D Now! op in both routines
	please for P3 use STD routine - Thanks to kolla for
	helping bite this bug.

	assert_stack() on startup - we must have min 16k

	Added MemTest binary for testing speed.
	
1.0	initial release
