Abstract
The present invention relates to an elementary cell of a linear filter for image processing, as well as to a corresponding module, element and process. The cell comprises a data circulation output and a calculation output, as well as a main delay line and an auxiliary delay line in parallel. Delay line selection means (MUX) make it possible to link the input of the cell to the circulation output by way of one or other of the delay lines. The cell also comprises an adder having two inputs which can be linked respectively to the input of the cell and to the output of the main delay line, by calculation selection means (MUX, MUX) and a multiplier at the output of the adder, connected to a multiplier coefficients memory. Application to linear filtering for image processing and to random access for motion compensation.
