Motorola 68060 FPGA replacement module (idea)

Yes the ALU is a piece you could get from various places ready made. I was pondering the possibility of using the cache management systems out of the OpenSPARC core.

68060 is definitely microcoded to some degree, move , is split into two "standard operations". No doubt fancy addressing modes are split up into even more operations. The RISC cores (x2) seem to be able to handle register-memory operations on their own though.

Do we care so much about the size of the core anyway? If the aim of the game is the fastest 68k CPU, the fastest rated FPGAs tend to be quite big anyway. Unless we're squeezed for space I wouldn't worry about it.
