So how about 68k CPU on FPGA, and FPU emulator on one of the ARM cores?

You need two MMUs ?

Not a problem, I already program in assembler

If it's about emulating, we might be better off by just using x86 jit...

Than Haynies A30000 FPU board for 16x 68882 would be just right for you:

Yikes

If it is for fun, there shouldn't be anything x86 in it ;-)

ARM is about as much fun as x86...

That's why I don't care about it, no emotion at all. Like to use it to deal with all mass storage and ethernet.

Everything else, CPU/FPU/MMU are in the FPGA, and that's where the fun is ;-)

Great news about the advances on FPU development! I wonder what it's speed is like vs. the raw 68k speed of the Vampire CPU core itself.

Inclined to agree, pitched my pi3 next to a black edition vampire A600 last year and it was neck and neck.

Being affordable to everyone and not just a few is a major plus

yes and when new raspberry,s come out they git faster and faster so in the end will beat the vampire cool i love rpi3 its awesome.

every home should have some in they cool , ace at emulating all kinds of stuff.

Jaw. On. Floor.

Wow, they've really got it tightened up.

Time for some Quake demos!

Um, the slow one is the Vampire. The good news is that there is a lot of room for improvement. E.g. in the version used for the video the ea-decoding is done by the emulation code despite the fact that the CPU puts the decoded ea into the exception stack frame.

Ahh, OK, see I thought it was a case of the first video being the earliest release of the SoftFPU and the second being a newer revision. My bad.

Why is the 3D anim scene right before that so different on the two?
