Abstract[English]
A method of branch prediction includes, in a pre-execute loop, loading a series of instructions leading to a load dependent branch (LDB) instruction including a load instruction, executing the load instruction to receive a part of a branch condition, computing a branch outcome of the LDB instruction based on the branch condition, and storing the branch outcome to a branch-outcome memory. Then, in a main loop corresponding to the pre-execute loop, loading the LDB instruction, reading the branch outcome from the branch-outcome memory, and executing the main loop based on the branch outcome. In some cases, the method, in the main loop, computes the branch outcome of the branch condition again.[French]
Un procédé de prédiction de branchement comprend, dans une boucle de pré-exécution, le chargement d'une série d'instructions conduisant à une instruction de branchement dépendant de la charge (LDB) comprenant une instruction de charge, l'exécution de l'instruction de charge pour recevoir une partie d'une condition de branchement, le calcul d'un résultat de branchement de l'instruction LDB sur la base de la condition de branchement et le stockage du résultat de branchement dans une mémoire de résultat de branchement. Ensuite, dans une boucle principale correspondant à la boucle de pré-exécution, charger l'instruction LDB, lire le résultat de branchement à partir de la mémoire de résultat de branchement et exécuter la boucle principale sur la base du résultat de branchement. Dans certains cas, le procédé, dans la boucle principale, calcule à nouveau le résultat de branchement de la condition de branchement.
