25 wm-FPU-emu is an FPU emulator for Linux. It is derived from wm-emu387
31 My target FPU for wm-FPU-emu is that described in the Intel486
33 facets of the functioning of the FPU are not well covered in the
40 wm-FPU-emu does not implement all of the behaviour of the 80486 FPU,
56 ----------------------- Internals of wm-FPU-emu -----------------------
82 emulate each FPU instruction to completion without interruption.
99 ----------------------- Limitations of wm-FPU-emu -----------------------
101 There are a number of differences between the current wm-FPU-emu
102 (version 2.01) and the 80486 FPU (apart from bugs). The differences
