Encapsulation of large native operating system functions as enhancements of the instruction set in an emulated central processor system
This invention relates to the art of computer system emulation and, more particularly, to a computer system emulator in which the functions normally performed by the hardware in a legacy central processor unit are emulated by a software program.

| Zusammenfassung: | This invention relates to the art of computer system emulation and, more particularly, to a computer system emulator in which the functions normally performed by the hardware in a legacy central processor unit are emulated by a software program. The invention is to enhance the emulated instruction set beyond that of the legacy machine such to include as new single instructions a method for invoking operating system functions, with the machine coding of the operating system functions now being performed by machine code native to the new host machine, rather than as a sequence of emulated legacy instructions. |
