CVDR Algorithm For Asynchronous Network on Chip Design
To elucidate the influence of process variation on Network on Chip (NoC) design, all of router, interconnect and
routing algorithm are implemented as key elements in 2D-Mesh topology. The delay variation is the main motivation to
crumble the performance of routing algorithms with technology scales down. To avert the influence of process variation and
congestion for asynchronous NoC design, a novel routing algorithm is presented. Congestion and process Variation Delay
aware Routing (CVDR) algorithm is proposed as adaptive approach. At various traffic patterns, the improvement of CVDR
algorithm as compared to different routing algorithms under process variation conditions is measured. CVDR algorithm
performs better significantly than different routing algorithms, even under the presence of a process variation.
