New Buffee (ARM 68K Emulator) Accelerator In Development
Renee Cousins AKA Nonarkitten is developing a new open source accelerator with a 68000 DIP chip profile based on the Octavo OSD335x-SM ARM system on a chip running a new "PJIT" bare metal 68030 emulator. Blog posts

Interesting stuff. I saw it earlier today on Amitopia
https://amitopia.com/new-buffee-amig...ing-1000-mips/ I'll be shocked and amazed if they can keep that performance and have a high level of compatibility. |
this is a list of features posted today...
the basic control features we'll have in the EEPROM: - set the CPU instruction set (68000 or 68030) - enable/disable the FPU - enable/disable extended 881 FPU opcodes - enable/disable 68K MMU - change base PLL from 275MHz to 1GHz - change instruction rate from 1 to 1/256ths - enable/disable L1 or L2 caches - set the size and sets of the L3 cache - tweak timing of the GPMC - set the amount and location of SDRAM available - enable/disable peripheral windows into the AM335x - enable/disable execution of user ARM code More TBD as required |

can you make a A600 version of this? I would love to replace my V2

I look forward to trying it. |
Also very interested in this, especially because it'd be a drop in, baremetal solution. That Raspberry Pi thing someone had made, beats all purpose, by having to wait for a system to boot up, SSHing into it, etc...

Yep, totally agree with Akira. This is a more interesting project.

@Akira - well it is a system solution. It doesn't mean it has to be. It is that way because you can use system devices with their (already present) drivers and - eventually - "forward them" to AmigaOS one way or another. With custom solution and baremetal it's nearly impossible for a few enthusiast developers to get on-die peripherals working under AOS. Especially GPU or USB part - which indeed is Achilles' heel of many amiga related projects anyway. Even Warp limits usb functionality to mass storage and hid. Same with Vampire. And both accelerate only basic 2D with no 3D whatsoever (well, Vampire team might give some but I doubt it will make much of a difference, I find it hard to believe they'll squeeze enough room inside already existing v2 and v4 to hold any decent 3D accelerating engine). Besides - most 3D accelerated titles for amiga are ports from PC anyway.

These are awesome news! The more choices for kickass Amigas, the better!

Ok so it will probably many times quicker than loading linux with PiSTorm. PiSTorm already offers RTG and fast HDD with Wifi just around the corner (if not already implemented). |

This is a winner for when stocks of 68000 CPUs inevitably start to run dry. With the added benefit of providing optional accelerator features.
I see it as it's own thing not to be compared with anything else. I will be saving one of my A500s for a buffee :) |

I would like to try that on my A2000! We also need something like that for Big Box Amigas, A3000/A4000. These 2 computers are ignored since forever.
Is the price in CAD or USD? Price looks good. Coming Soon.. Weeks or Months? What will be the production scale, hand made, factory assembled? Thanks |

I am SO excited for this product, and for the team bringing it to reality. Pushing all the What Ifs and Could Yous aside, one solid moment of a sustained standing-O is first and foremost in order here.
I also very much want to thank you for aiming at the 68000 group of computers, too. Absolutely glorious time to be in the Amiga universe! I have a little ICD AdSpeed that works in a very similar fashion to this in terms of installation and shape, I think. It gives me a nice little 14Mhz boost. The BUFFEE... well, is like comparing a toy Hot Wheels car to a spaceship! Nonarkitten it sounds like there will be a "fallback" mode for that occasional time some old software timed itself off the CPU? I'm thinking something like... Ultima IV, to be very niche and specific. It was coded directly at 7mhz, so it's awful to play on accelerated Amigas. I. Can't. WAIT! If it isn't compatible with a Rejuvenator and/or Parceiro, I'll still happily get one for my A2K and pull the GeForce out of there to give this a go. GREAT WORK! So amazed and blown away by this exciting news. |
