Running any UAE (software emulated Amiga) on Power64 attracts WinUAE/Cloanto Amiga Forever PC competition. Reminder, Mike Battilana(of Cloanto)'s Amiga Inc owns "AmigaOS" 3.X name and related IP.

I have a classic AmigaOS 4.1 FE and when I run a WHDload classic Amiga game, it triggers UAE. There's no attempt to run 68K Amiga games in a virtual machine or a sandbox.

I didn't make the argument for FPGA PowerPC i.e. you inserted this argument.

I'm still waiting for "A500/A1200" replacement from the PowerPC/Power64 camp.

PowerPC/Power64 has IBM which is a problem i.e. at least Vampire V2's price range is near to A500's price range.

Where's your PPC solution that matches Apollo's Vampire price range FOR the Amiga platform?

Again, where's your PowerPC solution that matches Apollo's Vampire price range FOR the Amiga platform? Your argument is not complete when there is a cost factor for the consumer.

There is no sub £600 PPC solution apart from A1222 which is still not public yet. What the vampire team have achieved is amazing strange that it maybe 68k looks to have a better future than PPC Amigas at the moment. X5000 is way to expensive for a system that as of yet still doesnt use all the motherboards/cpu features.

Scrap PPC and move to Arm.

The A1222 also lacks a compiler for the esoteric CPU just like the Vampire, which is unsupported in current GCC. The Vampire has no compiler for AMMX, which is forever pending now in GCC. It's worse for the A1222 as normal PPC code will crash so needs an emulator to hack it in. But the Vampire can run common 68K code fine. Still, it may have been popular to hand optimise 68K back in the day, but expecting coders to port video players and hand optimise it to use AMMX is not practical.

Since Power ISA is open source and anyone can implement their own design based on that architecture, we can see new chips emerging based on the OpenPower architecture.
This SoC is very interesting for the Amiga and includes a GPU and a VPU in the processor.
It is designed to be very fast even if it uses low power. It is suitable for smartphones, tablets, laptops and workstations.
Since the teams are asking for collaboration, it would be nice if some talents from the Amiga world were to participate in this project.
For example, Hans De Ruiter is really very talented in GPU and would have in mind his own GPU to design. Gunnar is very good at CPU design (albeit on the CISC side). Others are good at FPGA and there are really good Amiga programmers around.

Yes it possible to make powerpc chip with right stuff, (some custom chip integrated), AltiVec, I love some real 64bit integer registers, some proper 64bit Interger load / store, instructions, found that actually had to use doubles to get 64bit register. It was copy function so did not realty care, it might be that 128bit AltiVec can also be used in some cases, 256bit SIMD instruction set might also really nice, but not sure how practical, my biggest problem, is because its a different language. Can’t remember the instructions.

Planar conversion using 16bit conversion matrix to 8bit,
128bit is 16 x 8bit gfx pixels, that’s 16 pixels that read / written in one operation.
(64bits) 8 bytes * 65535 = is only 524280 bytes, (5 Kbytes)
(128bits) 16 bytes * 65535 = is only 1048560 bytes (1 Mbytes)

I bet EUAE graphics is not optimized.

It’s no point now, because so few people have AltiVec, huge investment only for a few people.
another question comes to mind, if a GPU shader can’t do the same work, by using its trillion cores.

No doubt are things done really inefficiently.

This needs to happen, It would be most Amigan thing ever!


How about checking the guy leading the project, who's track record has for example collecting ~$250k funding for SBC in 2016 which funders still doesn't have. Explanations for delays are top notch and on level of best bullshit explanations ever heard in Amiverse. It's always someone elses fault, not because basic eletronics is hard.

Bonus sector! What little exists of LibreSoc is in python (Because he's software engineer he says), so Captain obvious says that it won't be ready any time soon (Tho it was supposed to be taped out last october, there might be a pattern here).

Perhaps they could get Ryan Czerwinski on board.

PowerPC vs. FPGA?

Well normally a CPU runs circle around a FPGA with a softcore doing the same business.

And no one would ever consider building using an FPGA as 68k replacement if the 68k would have been developed further. If we would have a source for a 400MHz 68k with 2 MB of cache, we would laugh about people tinkering on FPGA boards.

---

PPC boards in the performance range of a Vampire ?Some years ago you could buy a 400MHz Efika for around 120€.

But this discussion Vampire vs. PPS/Power is useless.

Vampire is a retro oriented product, a Vampire V4 might be the fastest 68k(!) Amiga compatible computer on earth and even cheaper than a used A1200 with an accelerator board.

Power is a dying CPU platform that is replaced by ARM in the embedded market, but even the lowest performance Power CPUs are running circles around an FPGA with a softcore (if available).

Vampires are fast as long as you compare them even against a heavily expanded classic system. But are utterly slow when PPC comes into the equation. I have seen the Vamp loading 10 times slower compared to my MacG4/Mos setup DevilutionX, I have run the riva benchmark in the past and my system appeared to be 5 times faster or so. Plus my Mac/Mos cost about half the price (with registration). There was/is a thread from ppa/pl (I think) where they benchmark the rendering of a LW scene. AFAIR only the highest end i7 were significantly faster than a G5/X5000 (and the G5 is 15 years old architecture) not sure this flatters UAE per se). But anyway, if you dislike emulation (i7/UAE), feel the need for speed and want to be chained on an archaic version of our preferred OS then Vamp, is all the way in. Perhaps this extra speed might enable better DeluxePaint results, lol ,'cause there isn't any real need for extra speed on OS3 :) Over years I 've read delusional comments that the speed of Vampire might/will enable new apps to be created/ported for a slightly more everyday usage of AOS 3.x. Most probably 99.99% of those people have no idea what they are talking about : take Wayfarer and its need on cpu circles when it comes to say: javascript, period. How on earth will this ever squeeze to an fpga (which appears to be 5-10 times slower than current competitive ppc setups)? Even when consumer priced FPGA might reach the speed of a modest G4 (during the next... decade), most probably the nowadays ppc OSes might have migrated to other newer architectures and the cpu needs for everyday usage will have grown even further.
