@ppcamiga1

You talk about underpower and youre just a fanboy of amigaone, this is the real stupid thing.

@moderators

This is one of the best reasons for ban a user, talking crap about the amiga on a "amiga" forum.

gunnar as i see it you achieve 060+ class speed on a vampire card!¿:O
this really aint bad.
as far i see the caches dont get recognized, or arent there any? if so i guess it could still have some serious impact, but i wonder if there is any space left.


The MIPS result in SysInfo is rubbish and can't be compared to a 68060. The Phoenix fpga CPU is doing some work though :). There was a fast memory bug fixed recently by Majsta that may help the results. I don't know why the system libraries still appear in "SLOW RAM". The caches may not show up in SysInfo as they are transparently handled in Phoenix because they are Writethrough with bus snooping instead of Copyback caches. Writethrough caches with bus snooping don't require the caches to be flushed by the OS so it may not be necessary to inform the OS that they exist. SysInfo detects a 68000 which had no caches or instructions to add them also. Gunnar could clarify the question about caches (and fast memory). It was a good question which I can't answer except to tell you not to trust SysInfo.

I see that a lot of work progressed since the start of the project. I can't wait to see the final results.
I want to see Doom running in 64 colors on A500/A600.
A500 KS 2.1, 1MB Chip, 68000
A600 KS 3.1, 2MB Chip, ACA630 32MB RAM
A1000 KS 1.3, 8MB RAM
A1200 KS 3.1, Blizzard IV 50MHz 64MB RAM
A2000 KS 2.1, 68030 25MHz, 6MB RAM
A3000 KS 3.1, 68030 25MHz, 16MB RAM
A4000 KS 3.0, 68040 25MHz, 16MB RAM
CDTV KS 3.1, 4MB RAM
CD32
(AROS BOX) Dead :(

Thanks.
Yes, I agree so far we are quite happy with the performance in comparison to the price of the Vampire.

Apollo/Phoenix has 2 caches.
One for Data and one for Instruction.
Having 2 caches is good for performance.

Apollo/Phoenix is the first 68K CPU which uses transparent caches.
We have designed the CPU on purpose to have transparent caches..

The new trick that Phoenix does is it snoops updates to the DCache and automatically cleans up the ICache. Because of this Phoenix can support Selfmodifying code and the "cache-clean" functions of the later AMIGA OS versions are not needed to be used.

This means old software should run fine  - even with caches enabled.

On the Vampire cards Phoenix runs with
Icache= 4KB
DCache = 4 KB

On the Apollo/Phoenix Card we want to run with
ICache = 32 KB
DCache = 32 KB

The Sysinfo results are real and you can compare Phoenix with any other 68K with them.

As probably all people know Sysinfos benchmark is difficult for Super Scalar CPUs.
This means the benchmark is written in such a way that a Super Scalar CPU can not make full usage of a possible 2nd instruction execution per cycle.
But this drawback does affect Phoenix and 68060 the same way.
The Phoenix Core can execute several instrutions per cycle.
While this features is NOT enabled in the current Vampire loads, Phoenix can do this.

Execution of 2 instrutions per cycle can be enabled in bigger FPGA systems
Like for example in the ApolloPhoenix card or in the NATAMI.

I don't know why the system libraries still appear in "SLOW RAM".

This just depends on the mapping options used.
Phoenix has some sort of tarnsparent MMU feature.
Phoenix  supports automatic MAPROM - loading of Kickstart to fastmem and "MMU" mapping it to Kickstart memory region.
Phoenix also supports re-mapping of memory slices.

I've configured it to map 1 MB of fastmem to "slow-ram" area.
This is good for game compatibilty as some games expect to find memory at $c00000.

Memory could also be mapped to Zorro 2 and or Zorro 3 range.
This way up to 64 MB are then visible and usesable in the Vampire cards
and 128 MB are useable on the Phoenix card.

I just saw this thread and I have read it all. First of all it is great to see there is new hardware coming out for the A500 and possibly in the future also the A1200.

However I have some questions; Will this expansion require the Vampire board? Or will it come on it's own? Will it be just 68000 replacement or will include extra FastRAM and IDE?

There are currently 3 products:

Vampire 500 (for AMIGA 500)
CPU ~ 60-70 Mips
64 MB fast
IDE


Vampire 600 (for AMIGA 600)
CPU ~ 60-70 Mips
64 MB fast



ApolloPhoenix(for AMIGA 500)
CPU ~ 180-200 Mips (planned/unverified)
128 MB fast
SDCard as IDE
.. and more more features

Thank you for the quick reply. That is indeed good news.
I'll follow http://www.apollo-core.com/ for any latest updates :)

The two Vampire Cards : Vampire 500 and Vampire 600
are developed by Igor Majstorovik (http://www.majsta.com)
The Vampire 600 is available already.
The Vampire 500 is in testing right now.

Igor will anounce the card I suppose.


The Phoenix CPU Core is designed by me.
So all information about it is first hand.

The Phoenix CPU card was produced in 10 units for developers so far.
We are currently testing it.
As soon as we donw with testing we want to sell it.
We plan to be ready for this in the next month.

Official announcements will then be made on our website.

In the future I would like to see A3000/A4000 version of this accelerator using the fastport adaptor. I believe that this speed is more suitable for big box Amigas.

And this reminds me, I wonder how Shapeshifter would perform on this accelerator?
A500 KS 2.1, 1MB Chip, 68000
A600 KS 3.1, 2MB Chip, ACA630 32MB RAM
A1000 KS 1.3, 8MB RAM
A1200 KS 3.1, Blizzard IV 50MHz 64MB RAM
A2000 KS 2.1, 68030 25MHz, 6MB RAM
A3000 KS 3.1, 68030 25MHz, 16MB RAM
A4000 KS 3.0, 68040 25MHz, 16MB RAM
CDTV KS 3.1, 4MB RAM

Chip memory access is up significantly too. Nice!

Your selling a separate phoenix cpu card? Is this indepenedent of the vampire 500 and 600 boards?
Is this just a stopgap before the apollo board or something different?
