CA 2370644

An image producing device includes two vector processors for conducting geometry processing for expressing the respective images in parallel to produce graphic element lists, a graphic processor for conducting graphic processing on the basis of the graphic element lists, and an arbitrator. The graphic processor includes two buffers for storing graphic contexts corresponding to the graphic element lists together with identification information on the graphic contexts, and a unit for reading a specific graphic context from the buffers upon inputting the graphic element lists from the arbitrator to conduct the graphic processing. Each of the vector processors produces the graphic element lists having, as their contents, the identification information of the graphic context specified by the geometry processing assigned to each of the vector processors.

L'invention concerne un dispositif de production d'image qui comporte deux processeurs vectoriels conçus pour assurer un traitement géométrique destiné à exprimer les images respectives en parallèle afin de produire des listes d'éléments graphiques; un processeur graphique destiné au traitement graphique sur la base desdites listes, et un arbitre. Le processeur graphique comprend deux tampons destinés à stocker des contextes graphiques correspondant aux listes d'éléments graphiques ainsi que des informations d'identification sur les contextes graphiques, et une unité permettant de lire un contexte graphique spécifique dans les tampons, une fois les listes d'éléments graphiques introduites à partir de l'arbitre en vue de procéder au traitement graphique. Chaque processeur vectoriel produit les listes d'éléments graphiques ayant pour contenu les informations d'identification du contexte graphique spécifié par le traitement géométrique affecté à chacun de ces processeurs vectoriels.
