A bidimensional Finite Impulse Response (FIR) filter of rank 2p+1 for processing data associates a "vertical" filter and a "horizontal" filter. Each filter includes 2p+1 cells and circuitry for vertically scanning the data according to stripes having a height of p data; circuitry for simultaneously providing on a first line a datum of a stripe, on a second line a datum of the former stripe shifted by p data, and on a third line, a datum of the still former stripe again shifted by p data; and circuitry for, at each clock time, connecting each cell input to one of the three lines.
