Abstract

Higher link bandwidth provided by three-dimensional Network-on-Chip (3D-NoC) relies on multi-path routing and traffic splitting, which inevitably leads to out-of-order packet delivery problem when facing unbalanced traffic congestion. Therefore, a reordering mechanism, often requiring reorder buffers, is necessary to guarantee in-order delivery of packets. The reorder buffers are expensive in terms of both resource and power consumption, hence it is of great significance to reduce the reorder buffer size in the worst case. In this paper, we propose a improved Ohm's Law-like traffic splitting method, named RB-OLITS, for reducing the worst-case…(more)
