This paper describes the architecture of a chip for performing the 2 D convolution.
The systolic architecture proposed by H . T. Kung (1] has been chosen for the array of basic cells but a second level
of systolic architecture has been introduced with the internai structure of a basic cell . The basic cell performs
multiplication/accumulation in a serial way with a systolic architecture at the bit level.Cet article présente l'architecture d'un circuit réalisant l'opération de convolution bidimensionnelle, dans le cas
usuel d'un masque de dimension 3 x 3 .
Les contraintes d'intégrabilité (sous forme d'un composant VLSI) ont amené à choisir une architecture systolique
à deux niveaux
- association systolique de cellules élémentaires de multiplication-addition de mots binaires ;
- association systolique de microcellules opérant sur les bits
