Abstract: The invention relates to a component with a large grain dynamically reconfigurable architecture for processing of data by processing units organized in rows and connected to each other through interconnections so as to enable processing in pipeline or parallel mode or in dependent rows mode. All data types may be processed and the component may process several applications at the same time. The choice of the grain, control at several levels with limited control interconnection resources and the data distribution circuit enable local or general reconfiguration of the component in one clock cycle.

It also relates to an interconnection system for performing this process. This system comprises a plurality of processors (P0, . . . , Pn) connected on a ring network by means of in each case a cell (C0, . . . , Cn) ensuring the transmission and reception of messages circulating in the ring, a reception module (R0, . . . , Rn) able to store the messages intended for the processor and a transmission module (E0, . . .

Abstract: A multiprocessor system is disclosed wherein the processors communicate between each other asynchronously while carrying out synchronous processing. Each processor is associated with a cell connected to its neighbors by a ring network through which circulate messages for the processors. Each cell recognized the messages for its associated processor and communicates them to the associated processor. Particularly utility is found in the area of processing image-related data.

Abstract: The motor of a motorised fan unit for a motor vehicle radiator lies outside the perimeter of the radiator considered in the direction of the axis of rotation of the cooling fan, while its dimension in the same direction is at least partly superimposed on the thickness of the tube bundle in the radiator. The drive motor drives the cooling fan, which is arranged facing the tube bundle, through a drive belt. The size of the assembly in the axial direction is reduced, and the motor does not interfere with the flow of air through the radiator.

Abstract: A device for regulating the flow of air through a heat exchanger has a multiplicity of shutters pivotally mounted on parallel axes and actuated by control means that include an actuating plate which carries a number of cam tracks of selected shapes. Each cam track is arranged to engage a corresponding cam which is fixed to a respective one of the shutters for rotating the latter when the actuating plate is moved. The invention is especially applicable to motor vehicle engine cooling radiators.
