Abstract: front page image
(EN)A self-adjusting multi-speed pipeline is disclosed. A self-adjusting multi-speed pipeline is aware of the required processing time of the slowest stages that are actually used in each cycle (102) and to adjust the clock speed accordingly (104). Intelligence is added to the pipeline to detect when one or more of slower pipeline stages are to be used in each cycle. A clock generator (104) observes these detection signals (102) and increases or decreases the clock period in each cycle. The speed of the pipeline is reduced only enough for the slowest stage in each cycle to complete its processing.
(FR)L'invention concerne un pipeline multivitesse autoréglable, qui identifie le temps de traitement requis des étages les plus lents effectivement utilisés dans chaque cycle (102), et règle la vitesse d'horloge en conséquence (104). Des informations sont ajoutées au pipeline afin de détecter les moments où un ou plusieurs des étages les plus lents du pipeline doivent être utilisés dans chaque cycle. Un générateur d'horloge (104) observe ces signaux de détection (102) et augmente ou diminue la période d'horloge dans chaque cycle. La vitesse du pipeline n'est réduite suffisamment que pour l'étage le plus lent dans chaque cycle, cela, pour boucler le traitement.
