The invention concerns a method for automatically implanting software functions on a set of processors. The method comprises at least: a step which consists in breaking down the software functions into elementary tasks (SW¿1?, SW¿k?, , SW¿N?); a step which consists in implanting the elementary tasks on the processors (HW¿1?, HW¿2?, HW¿3?, HW¿4?); a step which consists in controlling implantation evaluating parameters whereof a list is pre-established, a penalty being assigned when a parameter does not fulfil a given criterion; a step which consists in calculating implantation cost, said cost being the sum of penalties assigned, the selected implantation being based on said cost. The invention is particularly applicable for systems, such as for example radar systems, comprising a large amount of software.

La présente invention concerne un procédé d'implantation automatique de fonctions logicielles sur un ensemble de processeurs. Le procédé comporte au moins; une étape de décomposition des fonctions logicielles en tâches élémentaires (SW1, SWk, SWN); une étape d'implantation des tâches élémentaires sur les processeurs (HW1, HW2, HW3, HW4); une étape de contrôle de paramètres d'évaluation de l'implantation dont une liste est préétablie, une pénalité étant attribuée à l'implantation lorsqu'un paramètre ne répond pas à un critère donné; une étape de calcul de coût de l'implantation, ce coût étant la somme des pénalités attribuées, l'implantation retenue étant fonction de ce coût. L'invention s'applique notamment pour des systèmes, tels que par exemple des systèmes radar, comportant une grande quantité de logiciels.
