Booth algo 4 multiplication

Soit ici 4 opérations au lieu de 6 pour un multiplicande signé en complément à deux, le signe s'interprète comme l'opposé de la puissance de 2, poids du bit le plus significatif : -2 8 pour un octet, -2 16 pour un mot de 16 bits etc dans ce cas, un signe négatif entraîne une soustraction initiale.
