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: A method and apparatus for offloading processing tasks from a first computing environment to a second computing environment, such as from a first interpreter emulation environment to a second native operating system within which the interpreter is running. The offloading method uses memory queues in the first computing environment that are accessible by the first computing environment and one or more offload engines residing in the second computing environment. Using the queues, the first computing environment can allocate and queue a control block for access by a corresponding offload engine. Once the offload engine dequeues the control block and performs the processing task in the control block, the control block is returned for interrogation into the success or failure of the requested processing task. The offload engine is a separate process in a separate computing environment, and does not execute as part of any portion of the first computing environment.

Abstract: Various embodiments of systems and methods for dynamic binary translation in an interpreter are disclosed. An embodiment comprises a method for dynamic binary translation in an interpreter. One such method comprises: receiving non-native code comprising a sequence of one or more operators to be interpreted; building a static branch destination table associated with the operators, the static branch destination table specifying a static branch operator that branches to another operator in the sequence and a corresponding memory location to which the static branch operator branches; parsing the sequence of operators and building a cross-reference table that specifies a pointer to an operator function associated with the corresponding operator, an index of the operator in a native code sequence, and a call to a native operator; selecting a dynamic branch code template for the native operator; and based on the static branch table and the cross- reference table, emitting the native code sequence to be executed via a native processor.

Abstract: Methods and systems are disclosed, including a method for executing a non-native code stream on a computing system. The method includes forming one or more blocks of emulated mode code for execution on a computing system. Each of the one or more blocks includes a preamble and a plurality of operators ordered for execution in a predetermined sequence, wherein for a specified block the preamble defines one or more conditions required for uninterrupted execution of the operators included in the specified block. The method also includes assessing the one or more conditions associated with the specified block, and, after assessing the one or more conditions, executing each of the operators included in the specified block without assessing any of the one or more conditions between execution of the operators within the specified block.
