| Coldfire prototype, pics : Comment 26 of 67 | ANN.lu |
| Posted by _ on 27-Jun-2003 13:16 GMT | Now, does it emulate some instructions, only - or does it emulate a whole 68k CPU? And why should it do the latter, if the former fully suffices? (For old games we can run UAE, if the thing is fast enough...)
From the site:
Q:My understanding is that coldfire CPUs won't run 680x0 code, but that a SOURCE CODE translator is available to help convert code.
A: Wrong, The Coldfire CPU can run 68K code, but is missing a few instructions (only three or four) which will be emulated by software (Already developed).
There is a sourcecode translator to turn 68K code into Coldfire optimised code, making porting software very simple.
Q: Are you going to provide a 68K emulator?
A: Yes, for sure, it will be build into an onboard flash chip and loaded before the kickstart, you wont even notice its there.
Q: Which 680x0 will it emulate? A: It can emulate any 68K CPU (including ones never used on the Amiga), as for the CPU emulated, Well if it can be made software switchable it will be, (But at the moment it looks like it would make a very large file) If not then probably a 68020 although as the chip will be software flashable it could be flashed to emulate any CPU without any problem what so ever. |
