Evaluation of X Architecture Using Interconnect Length Distribution

摘要

In this paper, we propose a new Interconnect Length Distribution (ILD) model to evaluate X architecture. X architecture uses 45°-wire orientations in addition to 90°-wire orientations, which contributes to reduce the total wire length and the number of vias. In this paper, we evaluated interconnect length distribution of diagonal (45° orientations) and all-directional wiring. The average length and the longest length of interconnect are estimated, and 18 reduction in power consumption and 17 improvement in clock frequency can be obtained by the diagonal wiring in the experimental results. The all-directional wiring does not have large advantage as compared the diagonal wiring.
