  • Shared code management
    Patent number: 8225276
    Abstract: An electronic device and method are provided to enable the management of shared code. Code may be shared if the environmental configuration is suitable for execution of the code and the functionality of the code matches. An identifier is provided to correspond to the functionality for a unit of code. Examples of identifiers can include file names, function names, macro names and class names. A checksum may also be used to identify the functionality of the unit of code. An organizational structure is configured to have constituents corresponding to environmental configurations suitable to execute the unit of code. Examples of the organizational structure include a directory structure or a class structure. The various units of code may be stored in the organizational structure and located by the constituent in which they are located and their functionality determined by the identifier to enable sharing.

    Publication number: 20120177135
    Abstract: Exemplary embodiments allow users to interactively formulate and solve multivariable feedback control problems. For example, users can solve problems where a plurality of control elements are distributed over one or more feedback loops and need to be jointly tuned to optimize overall performance and robustness of a control system. Embodiments allow users to specify design requirements and objectives in formats familiar to the user. Embodiments can operate on tunable parameters to solve the control problem in a manner that satisfies the design requirements and/or objectives provided by the user.

  • DYNAMICALLY GENERATING STATICALLY-TYPED PROXIES FOR DYNAMICALLY-TYPED FUNCTIONS
    Publication number: 20120180025
    Abstract: Embodiments of the present application may simplify an integration of statically typed and dynamically typed languages by automatically generating an implementation of a statically typed native interface for a given set of dynamically typed functions. In an embodiment, functions in a dynamically typed language are automatically interconnected with functions in a statically typed language. Code that bridges and/or connects a statically typed interface and a dynamically typed interface embodied in the dynamically typed source code may be automatically generated. The statically typed interface may be provided by a user. Further, an extensible set of runtime rules that determine how to convert between statically typed and dynamically typed data may be provided.

  • Stage evaluation of a state machine
    Patent number: 8214783
    Abstract: The present invention provides a method and system for stage evaluation of a state machine model. Two types of transitions are used: first-stage transitions and second-stage transitions for a two-stage evaluation. In one embodiment, top-down processing and bottom-up processing may be combined using a two-stage evaluation. First-stage transitions are used with top-down processing while second-stage transitions are used with bottom-up processing. Certain conditions are used to determine if a switch from one type of stage processing to another type of stage processing is needed.

  • Dynamic generation of formatted user interfaces in software environments
    Patent number: 8209663
    Abstract: Methods and systems for selecting multiple entities of a model or models to set or change data of the multiple entities together in a modeling environment are disclosed. When users create or edit a model or models, information on the entities of the model or models is provided to the users so that the users can select multiple entities in the model or models. On the selection of the multiple entities in the model or models, the modeling environment dynamically generates a user interface for the selected entities of the model or models for displaying, setting or changing data of the selected entities together. The user interface may display data of the selected entities that is not common to all of the selected entities in a different manner so that the users can identify common data of the selected entities.

  • Processor-in-the-loop co-simulation of a model
    Patent number: 8209158
    Abstract: A model may be constructed and simulated using processor-in-the-loop co-simulation at a target device. In one implementation, a host environment may provide a graphical environment that facilitates construction of the model defined as a plurality of functional blocks. The host environment may receive, via graphical selection menus associated with the blocks of the model, an indication of which blocks of the model are to simulated at an external target device and which blocks of the model are to be simulated at the host environment. Further, the host environment may receive a command, that may be entered interactively by a user, to start simulation of the model and execute, in response to the command, co-simulation of the model at the host environment and the external target device.

  • Storing and maintaining consistency among folios holding associated information
    Patent number: 8209350
    Abstract: Some embodiments of the invention provide methods, mediums, and systems for collecting and updating associated information. The present invention also provides a method and system for managing associated information in one file structure. Associated information can be generated from a source file or data and a portfolio can be generated to collect and store the source file or data and the associated information. A portfolio can include multiple folios storing different aspects of information that are related to one another. Each folio can associate information with aspects of other folios. When a change has occurred on a folio, an update strategy is used to update related folios and a map may be optionally generated. The map may provide information that allows dependent folios to understand what was changed. The map may remain in existence until all the dependent folios have adapted to the change.

  • Model based network communications
    Patent number: 8200849
    Abstract: In an implementation, a model executing at a target device may use networking services integrated within the model instead of using networking services of the operating system kernel. Latency and non-deterministic behavior associated with using networking services of the operating system kernel may be reduced. Computer-readable media may include instructions for compiling a model, that represents a design, for execution on a target computing device, the compiled model including one or more software components for directly communicating with a network adapter on the target computing device to handle network communications. The computer-readable media may additionally include instructions for transmitting the compiled model to the target computing device, the model, when executed, providing control over network communications at the target computing device.

  • Handling parameters in block diagram modeling
    Patent number: 8196056
    Abstract: A mechanism for processing graphical block diagram parameter expressions is presented. The mechanism achieves optimal implementation of block equations in the execution (run-time) environment by defining a mapping between user-defined block parameters and a run-time version of the parameters. The parameter processing mechanism also pools like, non-interfaced parameter expressions, allowing reuse of both uniform and non-uniform data across constant block parameters in the generated code and during model execution. The parameter processing mechanism further maintains an execution structure that maps the run-time parameter expressions containing interfaced variables to generated code for the block diagram so that the interfaced variables appear in the generated code. This mapping thus allows for interfacing to the interfaced variables in the generated code from any execution framework.

  • Thin client graphical presentation and manipulation application
    Patent number: 8190400
    Abstract: A distributed graphical presentation and manipulation application executes as a thin client application in a network. The networked graphical presentation and manipulation application can generally be used without requiring a user to install any specific software prior to using the application. In one embodiment, code may be received from a server via the network. A local environment may be generated based on the code, where the local environment may be configured to display a view of a graphical model. A request to manipulate the view may be received within the local environment. A request for a manipulated view may be transmitted to the server based on the received request. The manipulated view may be received from the server. The received manipulated view may be displayed within the local environment.
