Thus, for example, an MS Windows compatibility layer is not possible on PowerPC hardware, since MS Windows requires an x86 CPU in that case, full emulation is needed."
"A compatibility layer requires the host system's CPU to be (upwardly) compatible to that of the foreign system. 
With some libraries for the foreign system, this will often be sufficient to run foreign binaries on the host system." This translates system calls for the foreign system into native system calls for the host system.
#MAC SO AN EMULATOR OR VIRTUAL MACHINE SOFTWARE#
"In software engineering, a compatibility layer is an interface that allows binaries for a legacy or foreign system to run on a host system.Most often, an emulator will be composed of the following modules: a CPU emulator or CPU simulator (the two terms are mostly interchangeable in this case), a memory subsystem module, and various I/O devices emulators."
"Typically, an emulator is divided into modules that correspond roughly to the emulated computer's subsystems. And Windows API calls and services also are not emulated, but rather substituted with Linux equivalents that are compiled for x86 and run at full, native speed." In Wine, the Windows app's compiled x86 code runs at full native speed on the computer's x86 processor, just as it does when running under Windows. Such emulation is almost always much slower than execution of the same code by the processor for which the code was compiled. "Emulation" usually refers to the execution of compiled code intended for one processor (say, x86) by interpreting/recompiling software running on a different processor (say, PowerPC). "The phrase "Wine Is Not an Emulator" is a reference to the fact that no processor code execution emulation occurs when running a Windows app under Wine. So sayeth the great and all-knowing Wiki: It sounds like an emulator trying hard to market and brand itself as not an emulator. BTW can anybody explain to me in layman's terms how WINE is actually different from an emulator? It converts code from Windows language to Unix language within the Unix based environment according to their website, but they are adamant that WINE Is Not an Emulator.
