In this paper, the authors attempt to study "Higher load in inner circle and lower load in outer circle", a phenomenon existing in 2D mesh NoC (Network-on-Chip) using XY source routing scheme. A deadlock-free Static XY/YX Selection (SXYS) scheme is presented. For any source/destination PEs (Processing Elements) pair, SXYS only selects one fixed routing path: XY or YX scheme. SXYS scheme also ensures that the packets flow is transferred along only one path, so that the packets flow will get to the destination in order.
