  • Identifying function calls and object method calls
    Patent number: 9032380
    Abstract: A device receives program code, generated via a technical computing environment (TCE) and including code that requires further processing to execute, and identifies one or more function calls or one or more object method calls in the program code. The device creates a control flow graph, for the program code, based on the one or more function calls or the one or more object method calls. The device transforms the control flow graph into a data flow graph. The data flow graph includes a representation for each of the one or more function calls or the one or more object method calls. The device generates hardware code based on the data flow graph, the hardware code including code that does not require further processing to execute.

  • Median filter for image processing
    Patent number: 9031349
    Abstract: A device determines multiple sets of parameter values associated with an array of pixels to be used to process an image. Each set of parameter values corresponds to a set of pixels, included in the array, that are aligned along a first dimension of the array. The device determines a set of median values corresponding to each of the multiple sets of parameter values. The device determines a median of medians value that is a median of the set of median values. The device excludes a portion of parameter values, included in the multiple sets of parameter values, from a comparison set used to determine an overall median value, and determines a first median parameter value of the comparison set. The device determines the overall median value based on comparing the first median parameter value and the median of medians value, and provides the overall median value.

The device may generate a modified current state value based on determining that the current state value is outside of the range of state values. The modified current state value may be within the range of state values. The device may modify a historical state value based on determining that the current state value is outside of the range of state values. The device may provide or store the modified current state value and the modified historical state value.

  • Creating and using array creation routines or a family of routines separate from algorithmic code
    Patent number: 9015681
    Abstract: A device obtains first program code that identifies a function, an input argument to which the function is to be applied when the first program code is executed, and a class identifier that identifies second program code that includes a set of routines. The set of routines includes a routine that identifies a manner in which a return value of the function is to be generated, when the first program code is executed. The second program code is stored separately from the first program code. The device executes the first program code, obtains the second program code based on executing the first program code, and executes the routine to generate the return value, based on the function, the input argument, and the class identifier. The device provides the return value.

  • REUSABLE COMPONENT IN A MODELING ENVIRONMENT
    Publication number: 20150095877
    Abstract: In an embodiment, a modeling component generated in a first modeling environment can be implemented in a second modeling environment. The modeling component is executed in the first modeling environment. A first behavior of the modeling component in the first modeling environment is obtained based on the executing. The modeling component is then executed in the second modeling environment. A second behavior of the modeling component in the second modeling environment is obtained based on the executing the modeling component in the second modeling environment. The first behavior is compared to the second behavior. Based on the comparing, it is verified that the second behavior of the modeling component complies with one or more modeling requirements of the second modeling environment. The second behavior of the modeling component may be implemented in the second modeling environment.

  • Automatic modularization of source code
    Patent number: 8997065
    Abstract: A device creates a graph based on source code, and analyzes the source code to identify private variables and functions of the source code and public variables and functions of the source code. The device determines, based on the graph, a size threshold and semantics-related characteristics of functions and variables for each module, of multiple modules, and assigns, based on the graph, the private variables and functions to a corresponding module of the multiple modules. The device reduces, based on the graph, a number of the public variables and functions assigned to each module, and generates the multiple modules based on one or more of the graph, the size threshold, the assigned private variables and functions, and the number of the public variables and functions assigned to each module.

  • Scheduling generated code based on target characteristics
    Patent number: 8990783
    Abstract: Embodiments can include computer-implemented methods or non-transitory computer readable media storing executable instructions. The method or instructions can perform execution scheduling for code generated from an executable graphical model, where the generated code is executed on a target. The method/instructions can perform execution scheduling for a first code portion having a first execution rate, and a second code portion having a second execution rate that is temporally related to the first execution rate. The execution scheduling can account for target environment characteristics obtained from a target, can use an execution schedule, and can account for optimizations related to the first code portion or the second code portion. The method/instructions can further schedule execution of the first code portion and the second code portion in generated executable code based on the performing.

  • Model-based retiming with functional equivalence constraints
    Patent number: 8990739
    Abstract: A system and method tests for functional equivalence prior to automatically retiming a high-level specification. An Intermediate Representation (IR) includes one or more graphs or trees based on the high-level specification. A functional equivalence (FE) analyzer determines whether one or more components in the graph meet certain value and state conditions and thus is a candidate for retiming. A bounded scheduler then retimes only those components that pass the FE analysis.

  • Representing geometry of a system in a modeling environment
    Patent number: 8990057
    Abstract: In an embodiment, an element, that represents an entity in a system, is generated. The generated element may be incorporated in a network that represents the system. The generated element may include geometry information about a geometry of the entity. The geometry information may be used in one or more computations associated with a simulation or an analysis of the system. The element may have a frame port that exposes a frame. The frame may represent at least a position and an orientation in a two dimensional or three dimensional space with respect to another frame in the network. The other frame in the network may be a reference frame that may be defined by a “world” that the system resides in. The generated element may be incorporated into the network by connecting the frame port to the network.
