Abstract: Systems and methods are disclosed for selecting parameters for use by a system. The parameters can describe a behavior of the system, which can be represented by a model having an input and an output. The model can include an operation representable by a matrix. The parameters can include the input and output ranges of the operation, the dimensions of the matrix, a noise value for the system, an overflow probability, a regularization parameter, and a desired number of accurate digits. A design environment can be configured to determine values or ranges of values for one or more of the parameters based on values or ranges of values of the remaining parameters. In some embodiments, the design environment can select, recommend, or validate a choice of datatype, minimum system noise, or the dimensions of the matrix. The model can be used to generate code, which can be used to configure the system to perform the operation.

Abstract: Systems and methods for providing metric data for patterns in a modeling environment are disclosed. In some aspects, contexts for generating metric data for a pattern are constructed. The pattern represents one or more computations executable in the modeling environment and associated with operation or behavior of a real-world system. The contexts include information about the pattern. The metric data is associated with one or more objectives with which the use of the pattern is associated. Code for the pattern for each context is generated. Metric data is generated for the pattern and under each context. The metric data of the pattern under each context is associated with the objectives. The metric data and the association are stored for use in providing information about or based on the metric data when the pattern is to be or is used in a model representing the real-world system.

Code for the sub-model may be used for the simulation or generated code for the duplicated portions of the program or model in the simulation or code generation of the program or model.

Abstract: A mechanism for identifying and adding files to a project manifest is discussed. A combination of techniques is used in order to identify the files that should be listed in a project manifest. The combined techniques include the programmatic examination of a storage location marked as associated with a project to identify project files. The identified files are automatically added to a project manifest. In one embodiment the identified files are subjected to filtering criteria before being added to the project manifest. In addition, embodiments of the present invention perform a static analysis of at least one file associated with the project to identify file dependencies. The identified files are also added to the project manifest. The integrated development environment (IDE) also provides a user interface enabling a user to manually add files to the project manifest.

The composite signal configuration element configures one or more signals of a composite signal having a selectable grouping of the one or more signals. Configuring signals of a composite signal allows for the selectable creation, editing, and separation of composite signals. In some embodiments, hierarchical composite signals may be selectably created edited or separated into individual signals. In certain embodiments the composite signal configuration element may include additional functionality for performing operation on the composite signal.

Abstract: A modeling system includes a graphical programming environment that receives a first graphical model from a user. The system may also receive a configuration control set for the first graphical model. A code generation engine converts the first graphical model into an intermediate representation (IR). A second graphical model is created from the IR and the configuration control set. The second graphical model is displayed to the user, and may be subject to one or more modifications. Code in a target language may be generated from the second graphical model.

Abstract: The present invention allows a multi-threaded process to access an un-shareable resource without modifying the multi-threaded process. A binder is created for the multi-threaded process to access the un-shareable resource. All requests from the multi-threaded process to access the un-shareable resource are intercepted by the binder and the binder decides how to redirect or reformulate the requests to access the un-shareable resource. The present invention allows a process to dynamically bind to an interface at run time to establish communication channels among multiple concurrent computing resources in a concurrent computing environment. Hence, a user can choose to change to use a different interface during run time of the process without terminating the execution of the process.

Abstract: Methods and systems are provided for modeling a multiprocessor system in a graphical modeling environment. The multiprocessor system may include multiple processing units that carry out one or more processes, such as programs and sets of instructions.

The nodes representing the processing units of the multiprocessor system may be interconnected to each other via a communication channel. The nodes may include at least one read element for reading data from the communication channel into the nodes. The node may also include at least one write element for writing data from the nodes into the communication channel. Each of the processing unit can communicate with other processing unit via the communication channel using the read and write elements. Code may be generated to simulate each node and communication channel in the modeled multiprocessor system.

Abstract: A system and methods are disclosed herein for modeling a mechanical system having body elements movable in at least two dimensions in a graphical modeling environment. The system and methods described herein allow constraints on body elements movable in at least two dimensions in the mechanical system to be generalized and represented by a single block in the graphical modeling environment. The system and methods described herein simplify the modeling of a mechanical system by allowing a user to construct a definition of generalized constraints through a connectivity table. Thus, it is possible to model a mechanical system in a graphical modeling environment with less than all the body elements represented by blocks in a graphical model.

Abstract: A mechanism to dynamically vary the amount of delay for an event-generated function call is discussed. The event causing the generation of the function call may be a signal-based event, function call event or some other type of event. A function call generating delay component is inserted into a DES model and dynamically adjusts the amount of delay to apply prior to generating and transmitting the function call to an intended target component. The function call generating component reads a value from an input port in determining the amount of delay. The identified value at the input port may be a signal value or an attribute associated with an event entity received at the port.
