An analytical model for segmented bus enhanced network on chip

Several analytical models have been proposed for wormhole-routing network on chip while there is few analytical model for fully adaptive routing. To the best of our knowledge, there is not analytical model for segmented bus. In this paper, a new analytical delay model presented for hybrid Bus-NoC. First we present an analytical model for segmented bus, then by improving the mesh analytical model, we try to combine mesh and segmented bus. And finally, by applying some simulation results for hybrid Bus-NoC architecture we show that the hybrid model achieve a good degree of accuracy under different working conditions.
