ADOOM on A600 running 22-35 FPS

[NovaCoder]

Sounds better with the Prisma card

Hi

here is  Video showing how ADOOM in full screen mode runs on Amiga 600.

Impressive...well done

Now can we have the same thing for 1200/3000/4000 please with a bigger FPGA and more memory... Thanks

[NovaCoder]

The next generation cards are in testing and will come...
In parallel we work on making the CPU fully 68060 compatible.... But faster much faster...



Nova, when you ask for more memory..
Are the any games you work on, e.g. like Scumm games which need more than 64 MB ?

Quake 2 really needs 128 MB, DosBox could probably also do with 128 MB.

NetSurf could certainly use as much memory as it can get.

It seems pointless to create new fast processor boards and then cripple them with limited FAST RAM.   Ideally you'd go for 512 MB but if that's too expensive then go for 256 MB.

If we get enough MIPS then ambitious projects like DosBox can be usable on real hardware without using an RTG card.

I also do not see the point in limiting fast RAM, just go for 2GB and be done with it.

In an ideal world then yes that would be awesome but things are not always that simple.   The OS has some issues accessing more than 512 MB and the hardware becomes more complicated to build (cost and time to develop go up).   You also have to think about what applications would need that much, really there's not much.

As long as a new Accelerator had say 256 or 512 MB RAM then it should be enough.    

The only other thing I'd consider adding is an HD controller (SATA would be ideal).

If you start adding graphics chips and USB etc the complexity goes up for the hardware and the development of the drivers to actually use these extras.

But the biggest issue I have with sticking an off-the-shelf FPGA computer inside a Classic case is that it will turn my A1200 into a retro keyboard!

If you simple want to 'play' around with an modern mini-computer then you can just buy a Raspberry Pi instead.  You could even stick it in an old A1200 case if that's your thing

I think the biggest market for an FPGA accelerator is in something cheap and configurable (can emulate different hardware 030/68000/060 all with or without FPU)...something very similar to the Vampire with more power and memory.  

And then make it available for all Classic Amigas

[NovaCoder]

And btw my W7 PC has had 32GB of ram for over a whole year now.  Why can't my Amiga have 2 lousy GB?

Hiya,

Like I said above, 2 GB in a new FPGA based accelerator would be very cool to see BUT if it's going to increase the cost or development time (significantly) then I don't think it's worth it considering how these boards will be used 99% of the time.

This AGA port needs 400 MIPS to be usable (give or take)

Maybe one day

[NovaCoder]

How to you estimate the 400 Mips requirement?
How many times faster than a 50 Mhz 68060 would the system need to be?

400 MIPS was just a guess, I know that 100 MIPS on my 060 falls a long way short.

WinUAE with 800 MIPS and it flies

[NovaCoder]

Back OT, I would prefer to have a one that has fast 060 with a fast buss, plenty of memory,"loved 128M on my Tek card before it died" and SATA. I'll take 1 for my A2000 & A4000T.

PS: the 4KT really should have 256M.

Yes that's what I was saying earlier on this thread.

Obviously the Classic HW market is small these days but a single FPGA card design could be adapted for all Classic Amiga's without too much effort.   If such a card was priced competitively then it could be worth it.

[NovaCoder]

Let's not get too caught up in the specifics, it's very impressive stuff

The future in Classic hardware is FPGA!

[NovaCoder]

Thanks
 


What would be the pricepoint in your opinion for the FPGA/ASIC?

Lets say we wanted to build a new retro AMIGA with 600 MHz 68020 performance, fast FPU
256 MB fast memory, SAGA (truecolor) chipset ...
What in your opinion is the price break for the FPGA of such a system?
At which price you would say the FPGA is ideal for this?

I hate to say it but it would have to be around $200 to sell big (relatively speaking).    You can already buy an awesome retro computer for $50.

You'd still sell some at $500 but not that many I think

[NovaCoder]

The terrasic stand alone system you can buy already today.
They are professional FPGA boards not done buy us.

The NATAMI was sold to a limited number of users.
If /When Thomas will sell again - I do not know and can not answer.
But the option to have more than 68060 CPU power and at the same price reduce the cost as 68060 does not need to be bought, makes sense.
.

I take it you know about this?

A1200 accelerator interface

[NovaCoder]

Anyone have Vampire600 and Indivision ECS with P96 driver to show off?

Yep good idea, forgotten about that.

Or how about one of these?

Or DOOM direct-chunky 256 color mode?

[NovaCoder]

because one needs to start somewhere?

At the time the A600 user didn't have a lot of options whereas the A1200/3000/4000 users had quite a few cards to choose from.

Now the Vampire approach has been validated (high performance with low cost) then it makes sense to roll the same basic design out to all Amiga's.
