High-Level Interconnect Delay and Power Estimation
Résumé
It is now well admitted that interconnects introduce delays and consume power and chip resources. To deal with these problems, some studies have been done on performance optimization. However, as the results presented in this paper show, such techniques are not based on good criteria for interconnect performance optimizations. We have, therefore, developed a high-level estimation tool based on transistor-level characteristics, which provides fast and accurate figures for both time and power consumption. These results allowed us to create a new interconnect consumption model and also to determine new key issues that have to be taken into account for future performance optimizations.
