Abstract :
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 more layers are available for layout purposes. This study confirms that PRDT(2, 1) is a practical and promising topology for on-chip interconnection networks
