GXemul is an experimental instruction-level machine emulator. Several
emulation modes are available. In some modes, processors and
surrounding hardware components are emulated well enough to let
unmodified operating systems (e.g. NetBSD) run as if they were running
on a real machine.
The emulator is written in C, does not depend on third-party
libraries, and should compile and run on most 64-bit and 32-bit
Unix-like systems, with few or no modifications.
Devices and processors are not simulated with 100% accuracy. They are
only "faked" well enough to allow guest operating systems to run
without complaining too much. Still, the emulator could be of interest
for academic research and experiments, such as when learning how to
write operating system code.
