  • Dynamic on/off just-in-time compilation in a dynamic translator using instruction code translation
    Patent number: 9183018
    Abstract: Systems and methods for executing non-native instructions in a computing system having a processor configured to execute native instructions are provided. A dynamic translator uses instruction code translation in parallel with just-in-time (JIT) compilation to execute the non-native instructions. Non-native instructions may be interpreted to generate instruction codes, which may be stored in a shadow memory. During a subsequent scheduling of a non-native instruction for execution, the corresponding instruction code may be retrieved from the shadow memory and executed, thereby avoiding reinterpreting the non-native instruction. In addition, the JIT compiler may compile instruction codes to generate native instructions, which may be made available for execution, further speeding up the execution process.
