Patent

CA 2572954

One embodiment of the present invention includes a heterogenous, high- performance, scalable processor having at least one W-type sub-processor (74, 76) capable of processing W bits in parallel, W being an integer value, at least one N-type sub-processor (78, 80) capable of processing N bits in parallel, N being an integer value wherein and smaller than W by a factor of two. The processor further includes a shared bus coupling the at least one W- type sub-processor and at least one N-type-sub~processor and shared memory coupled to the at least one W-type sub-processor and the at least one N-type sub-processor (312), wherein the W-type sub-processor rearranges memory to accommodate execution of applications allowing for fast operations.

Un mode de réalisation de la présente invention inclut un processeur hétérogène, très performant et à géométrie variable comportant un sous-processeur de type W capable de traiter W bits en parallèle, W étant un entier, et au moins un sous-processeur de type N capable de traiter N bits en parallèle, N étant un entier inférieur à W d'un facteur deux. Le processeur inclut en outre, d'une part un bus partagé couplant le sous-processeur de type W à celui de type N, et d'autre part une mémoire partagée couplée au sous-processeur de type W et au sous-processeur de type N. En l'occurrence, le sous-processeur de type W réorganise la mémoire pour admettre l'exécution d'applications permettant des opérations rapides.
