Porting Photoshop?

Photoshop to the Amiga and make it run faster than on the
Mac?
The announcement was done some time (1/2 year or so) ago by
J. Drew and/or UU.
What happened to it? Vanished? Dropped?

Here's my scenario of what happened:
fade in, lobby of Adobe, Inc.
Adobe Receptionist: OK, let me get this straight.. You want to get our sources
to Photoshop and port it to a dead platform? Hold on, I
have to call my boss.
AR: Bob, there is some guy here who wants Photoshop sources. What? OK.
AR: He said "No fucking way."
AR: May I show you the door?

Bullshit, you never talked with them, they have never heard of you or UU.
Prove them wrong or shut the F*CK up.

Its Photoshop (no capital 's'). The current Power Macintosh product is an
accelerator that works with the emulated 68K application. It provides a
speedup of two to five times for the operations it accelerates. That
includes almost all the built-in filtering operations, but none of the
plug-in filters. Painting performance is much better than fully emulated,
but probably not as good as the faster Quadras. (I'm the engineer who wrote
this accelerator for those who question what I do at Adobe.)

Jim Drew has already said a number of things which are untrue as I can
collaborate them against my own knowledge. (E.g. nobody in the Photoshop
area of Adobe has heard anything about an Amiga port of Photoshop or of
Emplant demos.) This man's overall credibility is close to zero in my
opinion. However many of the things he says are just barely within the realm
of possibility, especially if you carefully evaluate them as half-truths.
The current Power Macintosh Photoshop accelerator does not speed up plug-in
filters. They are emulated. Obviously if you compare performance for these
against a machine with a fast 68K processor, they will run faster on the
native hardware than on Apple's emulator. So you get a bimodal performance
distribution and for certain applications, a real 68K Macintosh (or 68K
based Macintosh emulator perhaps) is better. This anomaly will disappear
when we ship the full native Photoshop with native plug-in filters. (And of
course there are lots of third party plug-ins which will run emulated until
the vendors ship new versions.)
Likewise, the AV DSP accelerator does not accelerate plug-in filters, only
the built-in ones. This is unlikely to ever change as Apple's DSP
architecture is already on the wane.
No how does this indicate that a hypothetical Amiga port of Photoshop would
be faster than the Power Macintosh version. (And the idea of getting a speed
increase from running multiple copies of a CPU/memory bandwidth limited
application such as Photoshop on a uniprocessor machine is pure fantasy.)
Another example of Jim's half-truth is that the PowerPC has special opcodes
for emulating the Intel x86 architecture. PowerPC does have a set of byte
reversing loads and stores which help the performance of emulating a
little-endian architecture. PowerPC also supports running in little-endian
mode for OSes like WindowsNT. These are certainly useful things to have if
running x86 software is a goal. However, these instructions are not going to
magically manifest Pentium class emulation performance on PowerPC hardware
that will be available in the next year.

Yes, and at the time they were accurate. I never spoke of Samsung but of an
Asian Investor, and there WAS an Asian Investor, that deal fell through.
: I don't think you have the exclusive on accuracy here!
You ave a problem reading I am afraid. Jim Drew was lying when he told
us he was about to go and port PhotoShop. I did not lie about the Asian
investor.

Don't knock ol' Paul here - he DID work for CBM and at the time, Ali WAS
negotiating with Samsung, hoping they would clear up his mess with loads of
$$$, a pipe dream that didn't quite work out, as we all know.
