Abstract: Embodiments of the disclosed subject matter can provide techniques for synchronizing data acquisition (DAQ) modules in a data acquisition system. In data acquisition systems where multiple DAQ modules are in use, it can be desirable to synchronize the DAQ modules to facilitate the analysis of signals captured by sensors coupled to those DAQ modules. This way, a signal processing platform, such as a computer, can analyze different sensor signals (e.g., an audio sensor and vibration sensor) without separately compensating for the time difference between the audio and vibration signals. In some embodiments, the synchronization techniques can include an automatic or a semi-automatic mechanism for temporally synchronizing the sensors and for arbitrating the sampling rate between the data acquisition systems.

Abstract translation: 所公开的主题的实施例可以提供用于在数据采集系统中同步数据采集（DAQ）模块的技术。 在使用多个DAQ模块的数据采集系统中，可以期望同步DAQ模块，以便于对耦合到这些DAQ模块的传感器捕获的信号进行分析。 这样，诸如计算机的信号处理平台可以分析不同的传感器信号（例如，音频传感器和振动传感器），而不需要分别补偿音频和振动信号之间的时间差。 在一些实施例中，同步技术可以包括用于在时间上同步传感器和用于仲裁数据采集系统之间的采样率的自动或半自动机构。

Abstract: A system and method may generate executable block diagrams having blocks that run in accordance with message-based execution semantics. A message may include an input data payload that does not change over time, and the message may persist for only a determined time interval during execution of block diagram. A verification engine may provide one or more tools for evaluating and verifying operation of message-based blocks. The verification engine may support one or more verification blocks that may be added to the block diagram and associated with the diagram's message-based blocks. The verification blocks may capture and present messages exchanged among the message-based blocks. The verification blocks may also specify an expected interaction of messages, and determine whether the actual messages are equivalent to the expected interaction.

Abstract: A device may receive function information that describes a caller element that calls a called element that is separate from the caller element. The function information may identify a name or reference of the called element, a passed input, and a passed output. The passed input may be provided by the caller element to the called element, and the passed output may be received by the caller element from the called element. The caller element may be associated with a caller model, and the called element may be associated with a called model. The device may identify the called element, and may execute the caller element in a simulation environment. Execution of the caller element may cause execution of the called element without causing execution of an entirety of the called model. The device may receive the passed output from the called element based on executing the called element.

Abstract: A system and method may generate executable block diagrams in which at least some of the blocks run in accordance with message-based execution semantics. A message may include an input data payload that does not change over time, and the message may persist for only a determined time interval during execution of block diagram. A message-based execution engine may control execution of message-based blocks in which a source block may generate a message at a particular point in time, the message may be sent to one or more destination blocks triggering execution of those blocks, and the message may be destroyed on or after a determined time interval. Other execution domains, such as a time-based or state-based execution domain, may be provided, and the system may implement a hybrid execution model.

Abstract: A system and method automatically generating one or more message sequence diagrams based on an analysis of the execution behavior of a model, such as a computer-generated, executable graphical model. A model analyzer examines execution instructions generated for the model. A filtering unit identifies execution instructions that concern designated elements of the model. An auto diagram builder generates one or more message sequence diagrams. The diagrams may include display features that represent activities involving the designated model elements. The diagrams may show the relative execution time order of the activities.

Abstract: Exemplary embodiments provide adapted components that may be used by a computer program under different execution contexts. The adapted components may include platform independent source code which may be executed regardless of the execution context in which the component is deployed. Adaptation logic may wrap the execution context independent component in a wrapper. The wrapper may perform data marshaling between the execution context independent component and a computer program invoking the execution context independent component, or the host system on which the computer program is deployed. The execution context independent component may be adapted to a new execution context dynamically the first time that the execution context independent component is invoked in the execution context. Thereafter, the execution context independent component may be invoked statically without the need to re-adapt the component.

Abstract: A minimum resource FFT design may calculate the FFT for an input data series using minimal logic resources to implement the FFT. In one implementation, the FFT design may include a butterfly component for performing one or more complex addition and multiplication operations and outputting a plurality of results; a first memory coupled to the butterfly component, the first memory including a number of memory banks equal in number to the number of the plurality of the results; a second memory coupled to the butterfly component, the second memory including a number of memory banks equal in number to a number of the plurality of the results; and a control component to control reading and writing from the first and second memories and the butterfly component using a ping-pong access technique that reads and writes intermediate values to the first and second memories to implement the FFT.
