A600 + Vampire + Phoenix-CPU = running texture demo
The demo uses 320x256 screen with 64 colors (EHB)
Link to demo (Amiga executable) http://www.apollo-core.com/phoenix_demo4 Link to video showing the result http://www.apollo-core.com/bringup/onlyamiga.avi |

I think this is the most interesting development in the Amiga scene over the past few years
![]() We have our first functioning FPGA accelerator board (thanks to Majsta) and an advanced CPU core under development (Phoenix). Personally I find this direction much more exciting than a completely new motherboard design like the over ambitious Natami. The Vampire board itself is obviously a bit limited but it's only the first attempt at creating a Classic FPGA accelerator. If the Phoenix core can be properly developed by the community hopefully somebody will be given enough of an incentive to develop more advanced FPGA boards for A1200's and big box Amigas. The Classic community has a real opportunity here to develop a very fast and compatible CPU that can be based on a combination of instructions from 020/040/060. Because a modern board can have much faster memory access (and a larger cache) than the old Classic accelerators it should be possible to create a very special board. As far as I can tell, all we need now to move things forward are for some talented FPGA coders in the Classic community to invest in Vampire boards and help develop this CPU core. Would it be possible to set up some kind of bounty for this important project? Last edited by NovaCoder; 12 May 2014 at 03:52. |

Going fully open source is what's needed. Documentation, PCB schematics & layout , HDL and synthesis scripts, plus firmware.
None of this closed source... "released when its ready" rubbish |

@gunnar
run some genuine amiga benchmarks please. a synthetic one cannot give the public an idea about the actual performance as you may imagine. |

You'd be surprised at the FPGA skills that exist either in the community or at least are lurking around the edges. It looks like this Phoenix core is already basically 'working' so it might not take too much work to complete it. My dream would be for AmigaKit to sell FPGA accelerators with a warranty for A1200/A2000/A3000/A4000 at less than $200. These accelerators would all share the same basic design to reduce costs and would have a decent amount of FASTRAM (say 512 MB). The FPGA core would be constantly improved (speed/compatibly/enhancements) either open source or not. It would be really cool to have a new boot menu and choose if you wanted to start up with a 14Mhz 68020, Blizzard 1230 Mrk4 or 100Mhz Apollo 060....how freaky would that be ![]() I was thinking, how practical would it be to have an IDE/SATA controller on an FPGA based accelerator card (using a patched scsi.device) and then disabling the on-board IDE. I was thinking about the performance benefit of offloading the HD controller to a separate small FPGA CPU instance, not sure how practical or complicated that would be to achieve.

great job !
![]() Could we expect an improved a1200 version or 4000 ? But you did an amazing job already. ![]() |

Very cool
![]() ![]() I was discussing this graphics effect with PMC last week, and it's one of these cool demo effect that never gets old or out of style. It can always be made to look impressive. I can tell from how fast it runs on your A600 that there's a lot of CPU power in that accelerator board. Great job! |

Well, you sure got my like
![]() Is it possible to run this demo on a stock A600 ? Or 2CHIP+ 4FAST one ? |

It is possible but code needs to be rewritten because it uses FastRam space that you probably don't have with your memory expansion board.
To correct myself: On my site I uploaded demo who works on any Amiga, so you can use it. I was assuming that you were asking about the way I run it showed on my video. Last edited by majsta; 20 May 2014 at 11:26. |
