Résumé de la communication

Design space exploration is a delicate process whose success lay on the designers’ shoulders. It is often based on a trial-and-error approach. Some basic metrics can be used to guide this process. In this paper, we explore accelerating loops from C-based specifications. We built a framework in which a design style, such as software-oriented, ASIP-oriented, or ASIC-oriented design, can be specified. Then, we propose new loop-oriented metrics that deliver some insight in the memory-computation tradeoff. They help to determine which aspects of the design between data accesses and ALU/Control operations limit or allow leveraging the loop acceleration opportunities. We also propose an analysis process flow that allows targeting the main aspect that limit acceleration and the actions that can be made to improve this acceleration. We profile some benchmarks from the signal and image processing fields such as the Turbo Decoder and the JPEG algorithms.

Résumé du colloque

Notre colloque accueillera un conférencier invité de marque, expert reconnu internationalement et chef de fil dans l’un des thèmes liés au sujet principal. Ceci permettra de hausser le calibre du colloque et s’assurer d’une participation maximale de nos membres et leurs étudiants aux cycles supérieurs, ainsi que de la part de tous ceux qui sont impliqués dans la recherche tant au niveau académique qu’industriel.
