I want to talk to MikeJ before making any moves. I would like to hear what the big project of A-EON/Hyperion/iComp is first and find out if Cloanto is serious about moving toward an open source AmigaOS. AROS certainly has advantages, especially with multi-core support, but AmigaOS is more efficient, more compatible and smaller. |

but it would be some wasting of the already integrated HDMI port.... Ok - let's go for a dual monitor setup Quote:

Gorf, are you Sorgelig?

FPGA 68k + ARM makes sense as a spiritual successor to 68k + PPC. Some kind of PowerUP style kernel for the ARM?

Why would anyone want a standalone vampire? Same reason.
For me: My real 68k Amigas are getting old, have no hdmi, are big and noisy. UAE is nice, but does not "feel" right sometimes. And I love to have a dedicated computer for AOS. UAE4ARM should be slower than Apollo on that FPGA. Last edited by Gorf; 02 July 2017 at 14:59. |

A linux kernel would run there as a "universal driver", but than you can e.g. run AROS-hosted on the ARM side. Via "Sunaj" (a reverse-JanusUAE) you could start ArosARM Apps from within the 68k-side.

At last, some sensible conversation going on instead of the constant bickering, arguing and bitching. I stopped visiting for a while because of it.
If someone built and sold what is been proposed here I would definitely have one, I have no interest in the Vampire at all since it's become clear there's not going to be a 68k compatible MMU and FPU. I didn't know about the MISTer project either, sounds awesome. Lets hope someone builds and sells them. |

Just use the linux you got working already on it, an focus on the amiga emulation. There is enough to work on ;-)

(a possible AROS-hosted would simply run onto of this kernel) That way the 68K side is free of some tasks (eg driving usb-ports) and just lets the linux-slave do the nasty work. |

Btw - MikeJ is working on using Raspberry Pi compute module as accelerator for the FPGA Archade, which would be very similar to the MiSTer in many respects.

So that is were my idea differs from MISTer. When using emulation od 68K on ARM, you need to go JIT to get good speed, but that is one of the reasons UAE does not "feel" right sometimes, because JIT gives you sometimes very high speed and sometimes not. On a CycloneV a core like Apollo should outrun a 68k_on_ARM-JIT most of the time. (One could even run both on this board next to each other and see what is faster ) Running in parallel to the ARM would also keep the ARM-side free for things like mp3-decoding (use it as a sound card) or video-decoding. Without slowing down the 68k (except for memory access). |

Speaking of something that gives you very high speed sometimes and other times not - Apollo Core is just like that. Quote:

ARm is nice for all the stupid work, like reading/writing sd-cards, usb sticks etc. Gives you nice Ethernet ... But the FPGA should do the CPU emulation and all the special chips ... |

Not really spending to much time on it, but an 800MHz ARM should be much slower than a 200MHz Apollo Core, if it really runs 1 OP per clock.

We should probably make a thread specific to the MisTer ...

No, emulating the chipset is hard stuff, depending on what the software tries to accomplish with the chipset, it can take a lot of resources. Unlike CPU usage that is quite predictable.
