What is the real power of Akiko chip in cd32 ?

[kolla]

So, now the numbers are there for a 030@50MHz + akiko and everyone is totally unimpressed. Yeah, that's what I thought, lol

[Iggy]

I would rather be brutally honest and aim for efficiency when I'm trying to be productive and then use the spare time to do things I enjoy with other hardware.

In my case, its the net equivalent anyway as what I WANT to do IS use an alternative, AND I only use the mainstream hardware when I really need to.

Also, I must again reiterate that I am highly offended by Microsoft's decision to integrate software that shares my personal information without requiring my permission, AND preventing its removal.

To be brutally honest myself, I don't like paying for the privileged of being spied upon.

I think they only make sense if you can compare them to basic a1200 or basic a1200 + 030.

Or the very same system, only using the 68030 instead of the akiko:

well, then its much more clear to me. compared to a basic a1200, the akiko seems to make quite a big difference: performance is almost doubled. this was already written on page 2 of this thread, but its nice to see someone confirm this

[steveuk]

does any talented amiga dev fancy making a CD32 (with fast) version of doom (either 4mb fast/8mb fast dont mind) ... that has CD Audio (eg. Doom 3DO music) optimised best possible for CD32/akkiko?

Happy to fund this project.

Woah - hang on a minute. I think Kolla's ratings were based on accelerators and Akiko, not just Akiko on its own.

You are looking at an accelerated CD32 for that, I reckon. Not common to find for sale.

Hi Pat
I did mean CD32 14mhz + Fast Ram.
eg. so it would be bootable if you had the SX1 upgrade attached, for example.

If you follow the thread back to the start; the results show the CD32 is approx same speed for Doom as 030/28mhz with Akiko Optimised.

Doom Attack:
Amiga CD32 68020/14Mhz 8Mb (Akiko Optimised C2P) - 12872 realtics (5.8 fps)
Amiga A1200 030/28Mhz 64Mb (Blitter 020 C2P) - 12727 realtics (5.8 fps)

and/or
Gloom:
68030/50+fast - 21.7 ms
68040/25+fast - 18.6 ms
68020/14+fast+akiko - 17.6 ms

This will mean Doom would be playable (on low res/windowed) and IMO would be well worth doing.

[Pat the Cat]

I guess sooner or later somebody will come up with a suitable accelerator, or maybe complete console that is CD32/accelerator friendly... dev costs just keep coming down, and it's not likely the internet archives are going to start shrinking.

OK. I see...... actually to be totally truthful, I don't, never really been a fan of Doom.

(slowly backs out of thread in shame).:flak:

My results are from CD32 50MHz 68030 + Fast RAM.

A1200 acc boards are shrinking, there are AFAIK no technical obstacles preventing something similar as ACA500 for CD32, "ACA32" if you like, that would let you use A1200 acc boards on CD32.

It's even easier for the CD32 as it's practically an A1200 slot on the back.

Disagree with your there. CD32 accelerators have a big problem - volume available, and airflow.

SX-64 was a hot little bugger - literally. Needed to put a fan on it in the summertime. Don't get me wrong, it packed a lot of Amiga goodness into a very small area. Lovely little machine. But, it was using tech from 20 years ago.

Anyway, that's hopefully where the TerribleFire is headed one day. Developer is feeling his way, setting size limits on board size, thinking about designing them properly. He wants to do a video breakout board first for the CD32, after getting some reliable A500/A2000 accelerator designs under his belt.

If you think about it, that's where the real lack is for Amiga accelerators - more A500/A2000s were sold than the others. CBM did make quite a few CD32s, didn't sell many, and there are still some quantities around.

Looking ahead even way further, maybe even chip replication will become available - not just for developers, but at the local library/college level. Want some custom silicon? Just upload it and wait for the chips to be delivered to your door. Now THAT would be cool. Custom design your own Amiga. With Akiko and a cherry on top.

Well, apart from the volume issue, that's true. A1200 is probably the most "developed" for aMIGA these days. There is a software base to work from, people want the hardware to run the software.

Arguable, really, as some people just want the 68K based Amigas to all expire from natural causes, and just develop around PPC.

I guess the most "tolerant" approach is to look at slaving any old processors to an Amiga bus, and let them choose which processor architecture they're going to use... which is kind of how WinAAE and the other emulators do it.

It boils down to how attached you are to the original hardware, I guess. Seduction. Love at first sight. That kind of issue. Very personal, of course. Very human.

EDIT: I know no shame. Never did.

Having a NEED to run Amiga software is different. Some of it kicks ass, even today.

I made a video driver for FUSION that uses the Aikiko for the CD-32/SX1 combo.  DEFINITELY worth the time to make the driver as the C2P is a lot faster than any 020/030 setup.

[Pgovotsos]

FWIW kippet2k has said a few times that he wants a Vampire for the CD32. Don't know if anything will ever come of it but he is a member of the team.
