A METHOD AND AN APPARATUS FOR REDUCING THE EFFECT OF LOCAL PROCESS VARIATIONS OF A DIGITAL CIRCUIT ON A HARDWARE PERFORMANCE MONITOR
(FR)
PROCÉDÉ ET APPAREIL POUR RÉDUIRE L'EFFET DE VARIATIONS DE PROCESSUS LOCALES D'UN CIRCUIT NUMÉRIQUE SUR UN DISPOSITIF DE SURVEILLANCE DE PERFORMANCES MATÉRIELLES
Abstract:
(EN)
The invention discloses a method and an apparatus for reducing the effect of local process variations of a digital circuit on a hardware performance monitor. The object of the invention to find a method and apparatus which both are able to reduce the mismatch between the read-out hardware performance monitor circuit and the design which is to be monitored as well as to minimize additional hardware effort and energy overhead for compensation of local variations will be solved by the following steps: - measuring a set of performance values c
n
of the digital circuit by n identical hardware performance monitors, whereas n is a natural number greater than 1, - determining an average value c
mean
of the measured performance values c
n
, as an approximation of an ideal performance value c
0
, - selecting one performance value c
j
of the set of performance values c
n
by a signal converter, - comparing the performance value c
j
with a reference value c
ref
by a controller, resulting in a deviation value ∆c, - controlling an actuator by using the deviation ∆c for regulating the local global process variations to the approximation c
mean
of the ideal performance value c
0
.

L'invention concerne un procédé et un appareil pour réduire l'effet de variations de processus locales d'un circuit numérique sur un dispositif de surveillance de performances matérielles. L'objectif de l'invention, qui est de trouver un procédé et un appareil permettant à la fois de réduire la désadaptation entre le circuit de surveillance de performances matérielles de lecture et la conception qui doit être surveillée, et de réduire au minimum l'effort matériel supplémentaire et le supplément d'énergie pour la compensation de variations locales, sera atteint par les étapes suivantes : - mesurer un ensemble de valeurs de performances c
n
du circuit numérique par n dispositifs de surveillance de performances matérielles identiques, n étant un entier naturel supérieur à 1, - déterminer une valeur moyenne c
mean
des valeurs de performances mesurées c
n
, en tant qu'approximation d'une valeur de performances idéale c
0
, - sélectionner une valeur de performances c
j
de l'ensemble de valeurs de performances c
n
par un convertisseur de signal, - comparer la valeur de performances c
j
à une valeur de référence c
ref
par un contrôleur, ce qui permet d'obtenir une valeur d'écart ∆c, - commander un actionneur à l'aide de l'écart ∆c pour réguler les variations de processus globales locales à l'approximation c
mean
de la valeur de performances idéale c
