20080263527 | PROCESSOR EMULATION USING SPECULATIVE FORWARD TRANSLATION - A method and apparatus for processor emulation using speculative forward translation are disclosed. A potential candidate for forward translation is identified from one or more portions of target system code. A priority for forward translation is assigned to the potential candidate. It is determined whether the potential candidate is a valid candidate for forward translation. If valid, the potential candidate is translated with a host system to produce one or more corresponding blocks of translated code executable by the host system. | 10-23-2008 |
20090164982 | METHOD AND SYSTEM FOR TRANSFORMING BINARIES TO USE DIFFERENT INSTRUCTIONS - In general, in one aspect, the invention relates to a method for transforming binaries to use different instructions. The method includes identifying an instruction in the binary, where the instruction is an unimplemented instruction of an instruction set of a processor. The method further includes replacing the instruction with emulation code, where execution of the emulation code emulates execution of the instruction, and generating an updated binary including the emulation code. | 06-25-2009 |
20090254891 | AUTOMATIC REVERSE ENGINEERING OF INPUT FORMATS - Systems and methods for automatically reverse engineering an input data format using dynamic data flow analysis. Combining input data with a simulated execution of the binary program using the input data and analyzing the use of the data by the program to generate a BNL-like grammar representing the input data format. The input data can be application level protocols, network protocols or formatted files. | 10-08-2009 |
20100262955 | METHOD FOR INTEGRATION OF INTERPRETATION AND TRANSLATION IN A MICROPROCESSOR - A method for executing a target application on a host processor including the steps of translating each target instruction being to be executed into host instructions, storing the translated host instructions, executing the translated host instructions, responding to an exception during execution of a translated instruction by rolling back to a point in execution at which correct state of a target processor is known, and interpreting each target instruction in order from the point in execution at which correct state of a target processor is known. | 10-14-2010 |
20110131557 | ASSEMBLY AND DEPLOYMENT OF MULTI-PLATFORM FLOW-BASED APPLICATIONS - A method and computer program product for assembling and deploying multi-platform flow based applications. An information processing flow that produces a result is assembled, the information processing flow includes components connected by data links, a component includes software code that describes at least one of an input constraint or an output constraint of the component, and at least two of the components are deployable on different computing platforms. The information processing flow is partitioned into sub-flows, such that for each sub-flow every component in the sub-flow is deployable on the same computing platform. The sub-flows are deployed on their respective computing platforms. | 06-02-2011 |
20110271260 | METHOD FOR SEPARATELY EXECUTING SOFTWARE, APPARATUS, AND COMPUTER-READABLE RECORDING MEDIUM - The present disclosure provides method, system, and computer readable medium for shared execution of software. The present disclosure relates to method, system, and computer readable recording medium for shared execution of software involving identifying the main modules of a specific software by analyzing its control flow, data flow, and modular structure through a static binary analysis and a runtime profiling, i.e. dynamic analysis, separating the modules from the main software body to store them in a secure environment of a smart card, and storing the main body in a user terminal with the identified modules removed and replaced by an interface code, whereby a co-processing the software at the user's end by the smart card in engagement with the user terminal exclusively enables an execution of the software. | 11-03-2011 |
20120159459 | OPTIMIZING SYMBOL MANIPULATION LANGUAGE-BASED EXECUTABLE APPLICATIONS FOR DISTRIBUTED EXECUTION - In one embodiment, a method comprises receiving an application that describes functions according to a prescribed symbol manipulation language, the prescribed symbol manipulation language a non-Turing complete language that does not permit partial functions and describes the functions independent of any attribute of any computing system; identifying, in the application, a distribution annotation that identifies a candidate element in the application, the candidate element configured for execution in a distributed computing operation by a distributed computing system comprising two or more distributed computing devices; generating one or more variants of the application based on executing a nondestructive transformation of the application relative to prescribed equality axioms, at least one of the variants containing a corresponding semantically-equivalent variation of the candidate element; and selecting one of the variants as an optimization for execution of the application by the distributed computing system relative to prescribed metrics. | 06-21-2012 |
20120167062 | EMULATING POINTERS - The present invention extends to methods, systems, and computer program products for emulating pointers. Pointers can be emulated by replacing the pointers with a pair and replacing each dereference site with a switch on the tag and a switch body that executes the emulated pointer access on the corresponding variable the pointer points to. Data flow optimizations can be used to reduce the number of switches and/or reduce the number of cases which need be considered at each emulated pointer access sites. | 06-28-2012 |
20130219376 | PLATFORM SENSITIVE APPLICATION CHARACTERISTICS - Systems and methods which provide platform sensitive application characteristics with respect to multi-platform applications are shown. As application aspects are developed in the application, embodiments include platform sensitivity characteristics for the application aspects in the application to provide for adaptation of application characteristics for multiple platforms. Embodiments provide an application runtime environment which, although independently defining its own user interface rendering attributes, operates to adjust application characteristics in accordance with a host platform. As application aspects of a multi-platform application are to be executed, if there are relevant cross platform differences, application aspect characteristics are adjusted so as to be appropriate to the host platform. The appropriately adjusted aspects are executed to thereby provide platform sensitive application characteristics with respect to the multi-platform application. | 08-22-2013 |
