Coldfire - Binary Compatible
« on: January 29, 2008, 08:56:04 PM »
Look what I just found at wikipedia:

"Newer models of ColdFire are compatible enough with 68k processors that it is now possible to create binary compatible Amiga clones. The Debian project is currently working on making its m68k port compatible with the ColdFires[1], as there are ColdFire models that are much faster than the 68060. They can be clocked as high as 300MHz, compared with 60MHz for a 68060 (the fastest "real" m68k processor) without overclocking."

Anyway, why Freescale didn't kept binary compatibility?
and... If that's true, is possible to design some newer boards with 300mhz Coldfires?

In my rumble opinion, FPGA is emulation. You code something generic to act like the real thing.
Makes no difference to me to take a x86 laptop with amithlon and TVOUT or a fpga "One chip Amiga".

Bloodline... Finally someone expressed my feelings about FPGA in a perfect way. Thank you.

Ok. in theory its not emulation, but...
It's always made through reverse engineering, to have the same behaviour of the original chip. But it's not made exactly the same. It's not the real thing.
As it's much more difficult to debug, the accuracy is probably much worst.

Besides my opinion about FPGAs, I also very excited about the MiniMig project. No one will create a special case for it? Like the OCM (One chip MSX)? Or maybe an A500 on a joystick?

And about the floppy emulator, that's amazing. When it will be ready!? :)
