Title
(EN) CLOCK COMPARATOR SIGN CONTROL
(FR) CONTRÔLE DE SIGNE DE COMPARATEUR D'HORLOGE
Abstract
(EN)
A clock comparator sign control is used in a compare operation. A clock comparator sign control that determines whether unsigned arithmetic or signed arithmetic is to be used in a comparing operation is obtained. The clock comparator sign control is then used in a comparison of a value of a clock comparator and at least a portion of a value of a time-of-day clock to determine whether a selected action is to be recognized.
(FR)
Selon l'invention, un contrôle de signe de comparateur d'horloge est utilisé dans une opération de comparaison. On obtient un contrôle de signe de comparateur d'horloge qui détermine si une arithmétique non signée ou une arithmétique signée doit être utilisée dans une opération de comparaison. Le contrôle de signe de comparateur d'horloge est ensuite utilisé dans une comparaison entre une valeur d'un comparateur d'horloge et au moins une partie d'une valeur d'une horloge d'heure de la journée pour déterminer si une action sélectionnée doit être reconnue ou non.
