DREADME2 | wm-FPU-emu an FPU emulator for 80386 and 80486SX microprocessors. |
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

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
