  • Patent number: 9864722
    Abstract: A communication system coupled to a data-acquisition circuit and to a data-processing circuit is provided, including at least one shift register, an addressing circuit and a multiplexer. The shift register includes a serial input for inputting and storing data in series, a serial output for outputting data in series, and parallel outputs for outputting data stored in the shift register in parallel. The addressing circuit is coupled to the shift register in order to identify the positions of stored data, and the multiplexer is coupled to the parallel outputs of the shift register in order to output the stored data to the data-processing circuit in series. Methods for communication between a data-acquisition circuit and a data-processing circuit are also provided.

  • Patent number: 9542719
    Abstract: A device for decomposing images into at least three levels by wavelet transform comprises a first unit executing a first level of decomposition and a second unit executing the higher levels of decomposition by performing a sequence of processing tasks. The tasks are ordered in time by using a sequence of rows, a routing unit serving to configure the second unit when the level of decomposition associated with the processing task currently being executed changes relative to the level of decomposition associated with the processing task executed previously. The processing tasks are ordered so that any given row is associated with only one level of decomposition.

  • Publication number: 20080263555
    Abstract: The invention relates to a method for scheduling the processing of tasks and to the associated device, the processing of a task comprising a step for configuring resources required for executing the task and a step for executing the task on the thereby configured resources, the method comprising a selection (1) of at least one level of independent tasks to be processed in accordance with an order of precedence and a step for sorting (2) out the tasks of the level of tasks to be processed in order to define, an order of priority in the processing of the tasks, depending on the number of resources required for processing the tasks on the one hand and on a time characteristic of the tasks on the other hand.
