Abstract: A non-native, multi-modal compiler and an emulated computing environment for use in a native computing environment. The multi-modal compiler includes a parser configured to parse or divide received source code into a plurality of token elements, whereby at least one statement is recognized from a collection of token elements. The multi-modal compiler also includes a code emitter configured to emit machine code to implement the at least one statement, whereby the emitted machine code is compiled multi-modal object code that includes non-native operators (e.g., E-Mode operators) and NATV operators. The compiled multi-modal object code is configured in such a way that when translated by a code translation unit, the compiled multi-modal object code generates a merged codefile having translated native code segments corresponding to the non-native operators and native code segments corresponding to the NATV operators. The merged codefile is executable by a native processor in the native computing environment.

Abstract: An emulation system that provides the functionality of an emulated computer on a host computer pre-processes the object code file to be emulated to reduce the run-time overhead due to parsing the object code. The emulator uses pre-programmed functions that model each instruction of the emulated computer. An object code file is pre-parsed to generate a translated file which includes a sequence of function calls corresponding to the sequence of instructions in the code file. The translated file is compiled to generate a corresponding translated object-code file. The translated object-code file is executed in the emulation environment on the host computer. The emulation system also includes a standard mode in which the object code file is emulated by sequentially parsing each instruction in the object code file and invoking an appropriate one of the preprogrammed functions in the emulated environment.

Abstract: An embodiment of the invention is a technique for enabling an emulator that emulates an e-mode program to utilize stored data items whose values are stored in native data format in native memory. The emulator fetches an item referenced by the e-mode program. The referenced item comprises a tag field and a data field. The emulator determines whether the tag field of the referenced item indicates that the referenced item is an external reference word (ERW). If the tag field of the referenced item indicates that the referenced item is an ERW, the emulator decodes the ERW to obtain a data type and a pointer. The pointer corresponds to a location of a stored data item in native memory.
