#76645 - RE: Microprocesor emulator? Responding to: ???'s previous message |
That's an interesting idea. But I suspect it probably complicates the project and the emulated system would probably be better emulated on a PC. A PC-based emulator might already even exist for running 6502 on a PC. In this case doing the same thing on an 8052 would be reinventing the wheel--though for the challenge it might be something to consider. And so, exist PC emulators of different 8-bit computers, with CPU and all the hardware emulated, but that's not the point. The point is to make an "open core" 6502 which could be "modified to your needs", and done in cheap, available '51 derivatives, and not in expensive FPGAs - and on chip, not in a big computer, so that can be implemented in your own application, like an "8-bit laptop" or replacement of a broken 6502 in an old Atari... Not something that could be achieved with a PC. A challenging yet interesting and often useful project. But when it comes to an "8-bit Atari-alike with 8052 CPU" I'd prefer to go with standard '52 CPU mode and not waste clocks on emulation. 6502-in-8052 being a completely separate project (though maybe optionally implementable?) |
