Implementing MVC Decoding on Homogeneous NoCs : Circuit Switching or Wormhole Switching

• To implement multiview video decoding on network on-chip (NoC) based homogeneous multicore architectures, the selection of switching techniques for routers is one of the most important aspects for design space exploration. Circuit switching and wormhole switching are two most feasible switching techniques for on-chip networks. To choose the suitable switching technique, we perform the comparison on decoding speed of the whole system, link utilization and delay between circuit switching and wormhole switching for implementing eight-view QVGA video decoding on 4 × 4 NoCs at 30 fps. The required link bandwidths are both around 800 Mbps with the similar network utilization and delay. We conclude that, to implement multiview video decoding on homogeneous NoCs, circuit switching is more suitable considering the similar performance and lower cost compared with wormhole switching.
