Yep. Back to doing more with less. This is what the 68k Amiga was good at and what most Amiga users have been doing since the '90s. Did you read the whole thread I linked? C= was planning a non-Amiga Hombre 64 bit game box but they also had plans to use the Hombre chip set for 3D gfx (card or integrated). They were planning to have it compatible with the Amiga and they were also planning an Amiga SoC (68k+custom chips). C= would have liked to continue both the Amiga and 68k but the 68k was more difficult as Motorola was sabotaging the 68k line as they tried to convert everyone to PPC and they were not known for making friendly licensing deals of their technology. C= seemed to aim too low in CPU specs also but some of that may have been Motorola's marketing and premiums they demanded on their chips. While it was unlikely that C= would have ended up with a 68060+Amiga SoC, it could have been competitive in performance/watt for over a decade for mid then low end retro gaming and embedded applications (set top boxes, kiosks, etc.). The 68060 had similar performance to the Pentium while using ~42% less power (5.5W vs 9.5W) and 32% less transistors (2.5mil vs 3.3mil). The 68060 could get away with 1/2 the memory of RISC for a further energy efficiency and cost advantage. A somewhat similar to the Pentium in order CISC Atom with the energy efficiency advantage the 68060 had compared to the Pentium would be outperforming the best Cortex ARM processors in integer performance/watt/core today.

CBM's take on "compatibiility" was gibberish.
I disagree with you on CD64 Vs Playstation 1 technicality, but I do agree with you that, with CBM trying to "manage" it, Hombre was screwed anyway. HP did do SOC with their first SIMD capable systems but with CBM's reputation, there was zero chance of it being an Amiga SOC. |

Moving the topic along a bit, I have had a look at this doc from the AMD Developer Guides http://amd-dev.wpengine.netdna-cdn.c...ation_v1.5.pdf Its quite interesting reading from page 18 onwards. You can either have the CPU push the data into the cards CP(Command Processor) or point it to a memory area and tell it to cycle through(pull) the data until you tell it to stop You kind of set up a `Copper List` of instructions for it to follow, I wonder where they got that idea? There is a list of Comand Processor registers from page 147 onwards. Would a SerDes have access to the memory onboard the Vampire card? So you could say have an interupt signal in your code that instructs the cards CP to use pull mode and grab a list of instructions from memory then wait until your next interupt If this is the case, then it is not imposible to get the card to do something. The programming of the shaders and vertex units looks very complicated and getting a `graphics card driver` up and running would be quite the labour of love. But if you look at the demo scene, they get a picture and sound out of almost anything you can solder together, program and wire up to an AV system. Hardware banging the card just to see what happens could be quite fun for the more adventurous programmers out there It could be 1987 all over again with a new copperlist and blitter registers to figure out! |

RPi3 can be used as graphic card for Amiga - USB interface with SPI and MIPI should be sufficiently fast for Amiga (flickerfixer trough MIPI), adding to this most complete (for now) documentation for GPU (video encoder/decoder still not documented), moderate power consumption, price - it will be very hard to beat in FPGA... Side to this Amiga can be beneficial from RPi community work (GPGPU).

Like seriously... dont beg for features from the board designers. we already try to cram on as much as we can for the money.

If the dreamers go too far, Im sure BigGun just do the cpt Picard facepalm move and then laugh.
I dont see the problem if people going off the deep end on forums, since developers can just ignore it, or simply say "NO, not going to happen!". |

Because it makes us rage quit eventually. Thats why.

Most people mean well and are enthusiastic, but the will to "participate" and add their own wishes or opinions will always be there in internet forums even when no one asked for it ;-)
As with life in general, you draw strength from the positives and ignore the negatives. Cheers |

if igor and gunnar were so easy to upset, that would have happened already. luckily not. that said, all these sensless proposals, usually insisted on by people who dont intend to bend a finger, actually are an annoyance. good thing they have an own forum.

I just think having a somewhat fast, expandable, cheap bus would be nice for big box Amigas. Right now we have the option of the sort of fast, very expensive and rare Grex or the slow (to motherboard and accelerator slot), reasonably priced and common Mediator.
Or maybe it's just too hard, whether it's from SPI to a PCI bridge or a PCI compactPCI controller on the Vampire with some ribbon cables. Don't blame me it's a wish fulfilling thread. |

Get a punching bag. Seriously though, you are blessed that Amiga people are interested in what you do. I'm lucky if I get any input on my projects and I'm usually ignored.

USB would be much more useful.

The developments of the Vampire team have mostly shifted from the CPU development to SAGA core at this point. Vampire supplies an SoC design like the RasPi3 thus a second one is unnecessary. SPI is available on the V500+. The stand alone units will not initially be card slot boxes AFAIK.

Correct me if I'm wrong but my understanding is:
SAGA = 24-bit modern HDMI display PC/HW = 24-bit modern HDMI display Why would you need two sets of display hardware that do the same thing? Also SAGA = relatively Amiga compatible, uses current GFX card drivers PC GPU = not really Amiga compatible would need drivers for each different card model. Why would Apollo team even bother with modern PC display hardware adaptors when their current method is functional and effective where an adaptor to allow an old PC GFX card is not? |

1) GPU performance in an FPGA can not match the GPU performance of even a semi-modern gfx card. 2) A gfx card offers more parallel processing power. 3) SAGA currently has no support for 3D. Reasons against an adapter. 1) Cost. 2) Transferring data through a bus is slower and increases latency. 3) Standardized integrated Amiga 3D gfx may be preferable to add in a FPGA SoC later, especially if planning an ASIC. |

Could a modern GPU somehow be added for 3D acceleration and other features without actually using it as a display output device? I think that's what you mean by "parallel processing power", but I'm not 100% sure. I can see how that might be a desirable feature. and one more question... But then how many Amiga titles actually make use of hardware 3D acceleration anyway? |
