Title (EN) MULTIPROCESSOR COMPUTING DEVICE
(FR) DISPOSITIF INFORMATIQUE MULTIPROCESSEUR
Abstract:
(EN) A computing device comprises a first processor configured to operate at a first speed and consume a first amount power and a second processor configured to operate at a second speed and consume a second amount of power. The first speed is greater than the second speed and the first amount of power is greater than the second amount of power. The computing device also comprises a scheduler configured to assign processes to the first processor only if the processes utilize their entire timeslice.
(FR) L'invention porte sur un dispositif informatique qui comprend un premier processeur configuré pour fonctionner à une première vitesse et consommer un premier niveau de puissance et un second processeur configuré pour fonctionner à une seconde vitesse et consommer un second niveau de puissance. La première vitesse est supérieure à la seconde vitesse et le premier niveau de puissance est supérieur au second niveau de puissance. Le dispositif informatique comprend également un ordonnanceur configuré pour attribuer des processus au premier processeur seulement si les processus utilisent leur tranche de temps entière.
