Abstract: The present mechanism obtains constraints within an interactive environment, associates these constraints with constructs, and then applies these constraints to the constructs when encountering the constructs. The constraints may be saved in metadata associated with the respective construct. The constraints may specify a data type for the construct, a predicate directive, a documentation directive, a parsing directive, a data generation directive, a data validation directive, or an object processing and encoding directive. The constraints are extendable to support other directives. The mechanism allows interactive users to easily specify constraints interactively.

Abstract: Dynamic translation of indirect branch instructions of a target application by a host processor is enhanced by including a cache to provide access to the addresses of the most frequently used translations of a host computer, minimizing the need to access the translation buffer. Entries in the cache have a host instruction address and tags that may include a logical address of the instruction of the target application, the physical address of that instruction, the code segment limit to the instruction, and the context value of the host processor associated with that instruction. The cache may be a software cache apportioned by software from the main processor memory or a hardware cache separate from main memory.

Abstract: The present invention discloses a method and system for specifying and executing computing tasks in a preboot execution environment in general, and, in particular, a method and system for generalized imaging utilizing a language agent and encapsulated object oriented polyphase preboot execution and specification language. The target customization is advantageously accomplished by encapsulating target dependent parameters in specification files. The target specific parameters are resolved at appropriate execution time when the parameter information becomes available. Such approach simplifies specification of complex tasks to a merely few lines of code. The approach of the present invention nevertheless affords reliable, robust, and accurate performance, because the pertinent parametric information are resolved only when they can be accurately ascertained. Furthermore, the specification encapsulations are themselves a part of the image set, providing self-describing images with self-contained imaging methods.

Abstract: A translator apparatus is provided with both program code interpreting and translating functionality, where subject program code is interpreted rather than being translated in those situations where interpretation of the subject program code is determined to be more beneficial. The translator applies an interpreting algorithm to determine whether a basic block of subject program code should be interpreted or translated. A particular subject of instructions supported by the interpreter functionality is initially selected from an entire instruction set for the subject program code. A basic block will be interpreted 1) if all of the instructions within a basic block are determined to be within the subset of instructions supported by the interpreter functionality, and 2) if an execution count of the basic block is below a translation threshold.

Abstract: The structure of a complex data object such as a multimedia presentation is stored in a persistent representation comprising a directly executable program. The instructions of the program are created by translating recorded method calls on a function library when the object is created. The structure of the object is recreated during playback by executing the program instructions in a stack-based virtual machine in a user's computer. The persistent representation thus stores the structure as a series of operations for building the object, rather than as a static plan of the structure itself.

Abstract: A system and method for controlling execution of an interpreted language. Statements of the interpreted language to be executed by a script engine are intercepted by a protection module and control is passed to a script helper module that is asociated with the script engine.

A special information block contains data as to the location of the interception points.

Abstract: A software compiler is described here that is capable of analyzing JTAG test functions and translating them into code and date usable and accessible by a JTAG-bus controller hardware circuit. The compiler is capable of reading instructions and data information not directly usable by a JTAG-bus controller, such as Serial Victor Format, and generating instructions and data executable by a JTAG-bus controller hardware circuit. This allows the JTAG-bus controller to directly access such compiled code during the test without using an interpreter to translate such information before executing them. The Compiler is also capable of allocating and managing a memory structure to store multiple data structure at the same time so that it will be ready to be used by the JTAG-bus controller during scan operations. This will allow for an expedited execution of the test functions since the data is already translated into directly readable and writable formats.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for reducing the power consumption of a microprocessor. One or more signal transitions in an instruction set of a microprocessor are profiled. A probability of occurrence is assigned to each instruction in the instruction set. A binary operation code is assigned to each instruction, based on the probability of occurrence for the instruction. The instructions having the highest probability of occurrence are assigned operation codes that require fewer signal transitions. As a result, the power consumption of the microprocessor is reduced.

Abstract: A method for analyzing the performance of a program when running in an interpreted environment. An interpreter is a program that translates and executes another program. To analyze a binary in an interpreted environment, a mechanism is used to indicate points in the program at source, intermediate, or binary showing where information about the system is to be tracked/profiled/analyzed. Once these analysis points are determined, triggers are created in a separate file or inserted via program instrumentation into the binary to indicate to the interpreter when the analysis triggers need to be processed. The system being analyzed is then run via an interpreter. When one of these triggers occurs during execution, the interpreter calls analysis code passing it the appropriate information so that it may track statistics, metrics, and information about the program corresponding to the trigger.

There are provided systems and methods for extending the capabilities of an application program for execution by a terminal. The application includes a script based workflow and non-executable content. One such method comprises loading the workflow for interpretation by a script interpreter, such that the workflow is configured for having a plurality of executable elements. This method also provides a global symbol structure for reference by the executable elements, the global symbol structure including addressing for coupling selected ones of the executable elements to corresponding external components.

Abstract: The invention relates to method for secure interpretation of a program in an electronic device. An interpreted program is loaded and a stub executable is formed using a prototype stub executable. The stub executable is associated with the interpreted program. At least one second capability also is assigned to the interpreted program and further to the stub executable. The stub executable invokes at least one function in a shared interpreter library to interpret the interpreted program. An interpreter engine checks whether the interpreted program refers an external interpreted program code section. The interpreter engine infers at least one second capability for the external interpreted program code section. The interpreter engine disallows the execution of said external interpreted program code section if said at least one first capability is not a subset of said at least one second capability.

Abstract: A high-level language, architecture-independent probe program compiler is disclosed. A base program is executable by one or processors, and has one or more breakpoints. A probe program is associated with each breakpoint and is also indirectly executable by the one or more processors. The probe program is independent of the architecture of the processors, and is generated from source code written in a high-level language. The probe program associated with each breakpoint is executed when the breakpoint is reached during execution of the base program. The compiler may employ an abstract syntax tree to switch between an address space of the probe program and an address space of the base program, by traversing the tree. Some of the nodes of the tree may more simply represent address space-specific objects of the base program. The probe program may be able to pass messages by manipulating the state of the base program.

Abstract: Generating program code to be used by a protocol analyzer based on definitional information relating to a data protocol. A protocol database that includes definitional information relating to characteristics of a protocol is stored. The definitional information, which is expressed in a computer-interpretable format, is processed to generate program code expressed in a programming language. The program code incorporates the definitional information and includes logic that is to be executed to interpret and analyze data packets having the protocol. In this manner, the program code to be used by the protocol analyzer is generated mechanically, without requiring software developers. When the program code needs to be updated in view of changes to existing protocols or the introduction of new protocols, the protocol database is updated. These updates are then propagated to the program code without requiring direct manipulation of the code by software developers.
