Does it have an MMU and FPU?
The 68060 and CM3 softcore does yes. The new hardware core is designed to replace the TG68K and the first priority is accuracy (required for the AtariST demo scene amongst others).
The fact it goes an order of magnitude faster than the current core in the Spartan7 is a nice bonus when required. We'll see how it develops. For the 68060/MMU/FPU the ARM SOC emulation offers the best price/performance ratio while keeping the rest of the system in the FPGA. I switch back to the internal core when accuracy is important (A1200/600/500 etc). I agree the TG68K is hard to maintain ( I do a lot of it), and it's important for the whole community we have a next gen open source core.
"I am a microchip developer by profession, I know VHDL. There is no chance in hell I could do architectural changes to Gunnar's core. "
So I am (actually a CPU designer). ^^ So, what you are saying is the core is unmaintainable by anybody else? Sounds like some poor design decisions there. Even very complex ARM designs are quite clean and can be maintained, which is a requirement obviously in a commercial environment. What happens to your customers if Gunnar gets bored then?
