English translation

You have asked to visit this site in English. For now, only the interface is translated, but not all the content yet.

If you want to help me in translations, your contribution is welcome. All you need to do is register on the site, and send me a message asking me to add you to the group of translators, which will give you the opportunity to translate the pages you want. A link at the bottom of each translated page indicates that you are the translator, and has a link to your profile.

Thank you in advance.

  1.  Calcul de la bande passante :

    Les valeurs des bandes passantes sont calculées en fonction des données du bus extraites de la base de données. Ces valeurs peuvent donc légèrement différer des valeurs habituellement mentionnées.

    La bande passante dépendant du nombre de cycles de données, quand le cycle de données est différent de 1/1, la largeur réelle de bande passante est mentionnée entre parenthèses dans la colonne en octets/s.
