Any missing features in 68060?

[Karlos]

Strictly speaking, is an FPGA implementation of an architecture considered an emulation?

[xyzzy]

I don't see the point in adding new instructions or addressing modes as it will only serve to frustrate people who want to run new code on original processors, and adding an illegal instruction trap handler to emulate them would slow things down a lot.

Larger caches would be nice though :-)

The primary goal should of course to be as simple as possible. And a 68020 can probarbly do everything that 030/040/060 can. Albeit slower.
My idea was if there were minor additions or bugs that one could have in mind when creating a softcore m68k.

Seems larger caches is one that could be implemented without wrecking compability too much. However any code should always have an switch to remain strictly compatible. Including bugs, as some software may rely on them.

A softcore 68020 is one stepping stone towards A1200,A3000,A4000,AGA etc..while there still exist original hardware to test any clones with.

I like the approach that the Natami team is taking with their vector unit.  They want to make the vector unit a separate processor so that it can be processing while the main processor does something else.

I also like that they are stripping out the multiprocessor support to make the addressing modes more orthogonal on the 68050.  This should make it easier to write compiler backends for it.

The 68050 is what used to be 68070?

@Kolla

The simple answer is yes.

The 68050 is not superscalar so it would not be fair to call it a 68070.  We aim to make the 68050 be a 68040 juiced up on steroids, with the MMU & FPU amputated.

i dont think i ever seen the thermal sensing pins used,perhaps i missed somthing.

Ok, I did a quick search on google for softcore and what came up was not exactly what I call IT related .. so anyone can explain to me what softcore (the IT type) is?

p.s. - please don't laugh.

An FPGA description of a CPU core... Which can be used to synthesize a CPU using an FPGA.
