Must be one with dynamic recompilation, using a really
advanced JIT. BTW, performance measurements when using emulators
with dynamic recompilation can be tricky: the code is surely
executed very quickly, but at some time it had to be compiled,
which takes certainly quite some time (significantly more than just
interpreting the code). Such systems tend to slow down when
loading programs or when executing very complex/big software.
I wonder how Transmeta systems behave, such systems must face
similar problems. It's more or less a simple RISC-CPU and an
emulation software layer with dynamic recompilation.
