Abstract

Selon cette invention, un appareil de traitement de données possède une unité centrale aménagée de manière à former plusieurs processeurs et connectée à une mémoire. Pendant l'utilisation, l'unité centrale échange un processus contre un autre et pour chaque changement écrit en mémoire une identification d'au moins un sur deux processus respectifs, et ce à un moment lié à la survenance dans le temps de l'échange respectif. La mémoire est surveillée par un système de surveillance qui stocke chaque identification avec une heure système indiquant le moment auquel l'identification a été écrite en mémoire et, partant, le moment auquel est survenu l'échange. Le système de surveillance peut ainsi déterminer quels processus sont en cours de réalisation pendant des périodes déterminées, tout cela n'ayant qu'un effet minimal sur le fonctionnement et sur les critères de conception de l'unité centrale. Dans un exemple, le système de surveillance détermine la proportion du temps dépensé pour chacun des processus étudiés dans chacune des fenêtres temporelles. Les résultats de cette analyse peuvent être affichés sous forme graphique, les fenêtres temporelles étant tracées sur un axe et les proportions sur l'autre axe.
