------------------------------------------------------------------------------
MuRedox is a MuLib based "on the fly" speedup patch for 68040
and 68060 based Amiga boards. The 68040 and 68060 do not implement
all instructions of the MC 68K family. The unimplemented instructions -
mainly FPU instructions - generate an exception and need to be
emulated by the 68040 resp. 68060.library. This is the job of the so-
called "FPSP routines" (floating point support package) within the
CPU libraries. MuRedox detects these instructions as soon as they
generate the emulator exceptions, runs a "just-in-time" compiler
that generates a "stub replacement routine" for this specific
instruction and patches the replacement routine into the running
program. Hence, MuRedox replaces the overhead of the emulator
trap on the next use of the same instruction sequence.
Therefore, MuRedox requires:
- At least an 68040 or an 68060. A 68030 or below implements all
instructions anyhow and does not require emulator traps at all.
- The mmu.library which is required to setup the special memory
mapping.
- The fpsp.resource. This resource contains the program code required
for most unimplemented math functions. This resource is made avail-
available by the mmu.library-based 68040 and 68060.library.
Therefore, installation of the "MuLib" libraries is *required*.
Please see the "MMULib.lha" package on Aminet how to install them.

History:
Release 40.7:
-------------
The emulation function for the 64-bit division instruction missing in the
68060 received a very minor improvement in case the divisor is larger than
16 bits.
Release 40.6:
-------------
MuRedox now also patches the fmovem.l #immed,<multiple control registers>
instruction which is unsupported on the 68060 - but probably so rarely used
that it hardly makes any difference. Though complete is complete....
------------------------------------------------------------------------------
Top reasons why not to use this program:
- It is a hack. MuRedox replaces program code on the fly, hoping that all
will go well. This need not to be the case - especially commercial
programs may keep a checksum over their code and may fail if their
code gets altered. MuRedox will perform such code modifications.
- MuRedox will therefore not work for all programs - some
incompatibilities should be expected.
If you need faster programs, you should rather:
- Ask the vendor for a 68060 or 68040 specific release of the program
that does not require the software emulated instructions of the 68040
resp. 68060. Typically, these versions will run faster than a
68020/68030 version with MuRedox, anyhow.
- Remember: Programs are made fast by fast and smart algorithms, not by
your favourite speedup-patch. MuRedox will give some speed impact,
in realistic situations in the range of about 10%. Specific bench-
marks may show more dramatic improvements, but they typically test
situations that are untypical in a real-life situation. Motorola
choose less frequently used instructions for software emulation in
first place, hence improvements are typically marginal.
