摘要： A computing system and method of executing a software program relate to translation of instructions for an emulated computing environment. The computing system includes a programmable circuit capable of executing native instructions of a first instruction set architecture and incapable of executing non-native instructions of a second instruction set architecture. The computing system also includes an emulator providing translation of non-native instructions into native instructions. The emulator operates within an interface layer and translates one or more non-native applications hosted within an emulated operating system for execution. The computing system further includes one or more translated memory banks defined at least in part by the emulated operating system and capable of native execution on the programmable circuit, where the emulated operating system is incapable of execution on the programmable circuit. The computing system further includes a linker configured to manage association of at least one of the one or more translated memory banks to the interface layer for native execution by the programmable circuit in place of a corresponding bank of non-native instructions.

摘要： Systems and methods for monitoring performance of virtualized instructions are provided. One method includes, during emulated execution of non-native program code including non-native instructions, maintaining a program flow history in a computing system representing a flow of program execution of the non-native program code. The program flow history includes a listing of non-native jump instructions for which execution is emulated in the computing system. The method also includes capturing one or more statistics regarding performance in native execution of the non- native program code on the computing system. The method further includes correlating the one or more statistics to the program flow history to determine performance of the computing system in executing one or more non-native instructions between each of the non-native jump instructions.

摘要： Systems and methods for testing and validation of translated memory banks used in an emulated system are disclosed. One method includes translating one or more banks of non-native instructions into one or more banks of native instructions executable in a computing system having a native instruction set architecture. The one or more banks of non-native instructions define one or more tests of execution of a non- native instruction set architecture. The method also includes loading a memory with instructions and data defined according to the non-native instruction set architecture and addressed by the one or more tests, and triggering, by an emulator, execution of the translated one or more banks of native instructions. The method further includes, upon detection of an error during execution of the translated one or more banks of native instructions, identifying an error in execution of the non-native instruction set architecture by the computing system.
