It consists in a global ontology with concepts shared by geotechnical experts and some local ontologies representing concepts and instances of a business. Geotechnical experts cooperate thanks to the global ontologie and mappings generated between concepts of different ontologies. Following this work, we study the effects of evolution changes in the local ontologies and mappings. We propose an appropriate approach which supports these evolutions in the geotechnical domain.","PeriodicalId":109795,"journal":{"name":"Tech. Sci.

In this paper, a High Level Synthesis (HLS) approach combining operation speculation and branch prediction is presented. In the proposed design flow, the CDFG (Control Data Flow Graph), is obtained by compiling the application. A speculation Graph is built. This graph allows to evaluate the potential of each branch to be predicted and the potential of each related Basic Block BB to be speculated. A target BB is then selected and scheduled using a list scheduling algorithm. A couple of BBs that will be predicted during the execution of the target BB is created. Operations of the couple are associated and speculativally scheduled in the target BB before being bounded to functional units. This step is repeated until all the BBs are scheduled. Finally, the RTL architecture is generated. The interest of branch prediction techniques in term of timing performances, and its impact on area are evaluated through first experiments.","PeriodicalId":109795,"journal":{"name":"Tech. Sci.

Des architectures dediees peuvent etre concues specifiquement pour un systeme. Toutefois, dans la majorite des cas, des processeurs generalistes sont employes afin de reduire le temps de conception et de mise sur le marche des systemes. L'utilisation de processeurs generalistes a cependant des inconvenients, comme la surface silicium occupee et son cout energetique. Cette inefficacite est en partie due a l'inadequation entre le jeu d'instructions des processeurs generiques et les besoins applicatifs. Cette inadequation est problematique lors de la conception de systemes embarques fortement contraints en surface et en consommation d'energie. Dans cet article nous proposons une methodologie permettant de reduire le jeu d'instructions du processeur et par voie de consequence sa complexite materielle afin de l'adapter au mieux aux besoins applicatifs. L'approche proposee a ete evaluee sur deux processeurs generalistes dont les architectures sont disponibles en open source. Les resultats obtenus demontrent que le gain moyen en ce qui concerne la surface et la consommation d'energie atteint en moyenne 20 % pour des implantations materielles sur cibles ASIC et FPGA.","PeriodicalId":109795,"journal":{"name":"Tech.
