摘要： System and method for configuring a system of heterogeneous hardware components, including at least one: programmable hardware element (PHE), digital signal processor (DSP) core, and programmable communication element (PCE). A program, e.g., a graphical program (GP), which includes floating point math functionality and which is targeted for distributed deployment on the system is created. Respective portions of the program for deployment to respective ones of the hardware components are automatically determined. Program code implementing communication functionality between the at least one PHE and the at least one DSP core and targeted for deployment to the at least one PCE is automatically generated. At least one hardware configuration program (HCP) is generated from the program and the code, including compiling the respective portions of the program and the program code for deployment to respective hardware components. The HCP is deployable to the system for concurrent execution of the program.

摘要： A method for determining timing constraints in dataflow models is disclosed. The method includes receiving node information specifying a plurality of dataflow nodes, as well as coupling between various ones of the dataflow nodes. The method further comprising receiving timing information specifying timing constraints for at least some of the dataflow nodes. Based on the node information, the couplings between the nodes, and the timing information, a timeline dependency graph (TDG). The timeline dependency graph illustrates a timeline, mappings between nodes with side effects to firing times of those nodes on the timeline, and dependencies between nodes.

摘要： A method for automatically mapping program functions to distributed heterogeneous platforms based on hardware attributes and specified constraints is disclosed. The method includes receiving a plurality of program functions and determining constraint information for each. The method further includes determining attributes of a plurality of hardware processing elements, wherein ones of the plurality of hardware processing elements have different attributes with respect to other ones of the hardware processing elements. The plurality of program functions may be automatically mapped for execution on at least a subset of the hardware processing elements, wherein the mapping is based on constraint information and the attributes.

摘要： Global optimization and verification of cyber-physical systems using graphical floating point math functionality on a heterogeneous hardware system (HHS). A program includes floating point implementations of a control program (CP), model of a physical system (MPS), objective function, requirements verification program (RVP), and/or global optimizer. A simulation simulates HHS implementation of the program using co-simulation with a trusted model, including simulating behavior and timing of distributed execution of the program on the HHS, and may verify the HHS implementation using the RVP. The HHS is configured to execute the CP and MPS concurrently in a distributed manner. After deploying the program to the HHS, the HHS is configured to globally optimize (improve) the CP and MPS executing concurrently on the HHS via the global optimizer. The optimized MPS may be usable to construct the physical system. The optimized CP may be executable on the HHS to control the physical system.

摘要： System and method for optimizing a data flow diagram based on access pattern information are described. Access pattern information for a data flow diagram may be received. The data flow diagram may include a plurality of interconnected actors, e.g., functional blocks, visually indicating functionality of the data flow diagram. The access pattern information may include one or more of: input pattern information specifying cycles on which tokens are consumed by at least one of the actors, or output pattern information specifying cycles on which tokens are produced by at least one of the actors. A program that implements the functionality of the data flow diagram may be generated based at least in part on the access pattern information.
