In this paper, we present PRDT(2, 1), a new interconnection network topology for Network-on-chip (NoC) design. PRDT(2,1) features a recursive structure, and has small diameter and average distance. We then focus our study on physical layout issues pertaining to PRDT(2, 1) . Specifically, we show that the minimum number of metal layers required for the placement and routing in a PRDT (2, 1)-based NoC is 2. We further demonstrate that the routing channel widths can be dramatically reduced when
