Evaluation of X architecture using interconnect length distribution
In this paper, we propose a new Interconnect Length Distribution (ILD) model to evaluate X architecture. X architecture uses 45 degrees-wire orientations in addition to 90 degrees-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 degrees 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.
