Some emulators, particularly those used by processor developers, are cycle-accurate, meaning that a particular instruction in a given context will take exactly as many cycles to run as it would on real hardware.

This meant that dealing with the dual architecture required very little work for the programmer, and just like the OS, applications themselves could mix and match 680x0 and PowerPC code fairly easily.

The compilers for Mac OS created such UPPs automatically when the proper macros were used, and the PowerPC system libraries contained native stubs to transparently call through to native or still-68k functions as needed. The 68k emulator then dealt with details such as presenting passed parameters in the right order for the ISA in question, as well as starting and stopping the emulator as required. From PowerPC code, this UPP could be passed to the CallUniversalProc( ) function to call it. However, it actually led to a data structure which contained a special trap instruction and flags indicating the instruction set architecture (ISA) of the called code. For 68k code, this pointer appeared to be an ordinary pointer to code and could be used as such. This was achieved using a new type of pointer called a Universal Procedure Pointer (UPP). The 68LC040 had no floating point instructions, making this feat slightly simpler but no less impressive.įor the programmer, the transition to the PowerPC was made fairly painless, because the emulator was started and stopped automatically. This emulator was theoretically capable of emulating 680x0 code faster than any real 680x0 was capable of running it. The emulator could recognise the same sequence of 680x0 code and run the previously-cached PowerPC code to avoid doing the translation again. Dynamic recompilation works by 'recompiling' common sections of the code into faster, PowerPC-native, sequences that were locally cached. For the PCIPowerMacs, the dynamic recompilation emulator was used to boost performance. Early versions emulated it by decoding each instruction and immediately carrying out a series of equivalent PowerPC instructions. Apple developer documents indicate that the emulator provided an operating environment most closely resembling that of the Macintosh Centris 610, a system based on the Motorola 68LC040 microprocessor. Macintosh OS 8.6 with Microsoft Internet Explorer 4.5 and Outlook Express 4.5: Macintosh OS 9.2 with Microsoft Internet Explorer 5 and Outlook Express 5: Macintosh OS X 10.2 (Jaguar) with Microsoft Internet Explorer 5.2 and Apple Mail: Macintosh OS X 10.4 (Tiger) with Safari 2 and Apple Mail 2.All versions of this emulator emulated the 'user' subset of the 68EC040instruction set with a 68020/68030 exception stack frame.
