Design of portable battery operated multimedia devices requires energy-efficient multiplication circuits. This paper proposes a novel architectural technique to reduce power consumption of digital multipliers. Unlike related approaches which focus on multiplier transition activity reduction, we concentrate on dynamic reduction of supply voltage. Two implementation schemes capable of dynamically...

In this position paper we investigate the use of dynamic analysis to determine commonalities and variation points as a first step to the migration of similar but separate versions of a software system into an integrated product line. The approach detects forks and merges in different execution traces as an indication of variation points. It is illustrated by a simple implementation, which is ap...

Statistics of frame-level pitch have recently been used in speaker recognition systems with good results [1, 2, 3]. Although they convey useful long-term information about a speaker’s distribution of f0 values, such statistics fail to capture information about local dynamics in intonation that characterize an individual’s speaking style. In this work, we take a first step toward capturing such ...

résumé – Une mesure de la part de variation expliquée par les modèles dynamiques de réseau On propose une mesure de la part de variation expliquée par un modèle stochastique de la dynamique des réseaux sociaux complets. Cette mesure est fondée sur l’entropie de la distribution des choix faits par les acteurs au cours du processus d’évolution du réseau. Elle a pour but d’aider à effectuer une me...
