Short: 68881 fpu emulator (source) Author: Azalin Uploader: c gujahr gmx de Type: util/misc Version: 1.0B Requires: 020+ Architecture: generic Please note: this program _will_ hang your computer and I am in no way responsible for what happens. When you run this program and your computer hangs or something else happens it is your own fault! The program fools AIBB and Sysinfo (they hang your computer, because NOPs get generated instead of floating point ops, you get no guru and the computer just appears to do nothing, or maybe it will crash spectacularly). That's why I didn't include an executable. The other reason is that my Amiga is currently in a box so I couldn't compile it anymore (and I don't have a monitor temporarily so that's another problem). The 'working' part of the sources is that short asm file (okay I'm definitely not proud of it but it took me some time digging through manuals to find the info I needed, mainly because I didn't have the good books though). The actual original intention was that the program would emulate the fpu on the PowerPC 603e for the fpu-less 040 or 030 in the original announced Blizzard PowerUP boards. Perhaps this still can be done, perhaps it's faster to emulate everything on the PPC because there's less overhead of communication between processors. History: I began writing this as I didn't feel like re-installing all kinds of software that required a floating point unit. This was when I sold my 68881 and memory card and waited for the Blizzard 1230/50 to come out. When it came out I stopped writing the program. I have included a bit of floating point emulation in c++ from the Amiga emulator for people who want to continue this project. (Oh well, it's only a few lines long but it did work a little.) My Amiga's are: Amiga 3000 (only a harddisk in it), Amiga 1200 (unexpanded, I sold all peripherals and the harddisk is the swapdisk in my -non-Intel- PC on which I run UAE sometimes).
