Design of a Crosspoint Queued Router for a Micro-network in SoCs

摘要：

Due to the advancement of manufacturing process for integrated circuits, more functional units can be integrated into a System on Chip (SoC). It causes the challenge of communication aspect in a SoC. Therefore, the design of Network on Chip (NoC) was proposed. Most research of NoC employs a kind of Input-Queued (IQ) switch architecture with VOQ (Virtual Output Queue) scheme. In this study, we apply a different switching architecture, Crosspoint Queued (CQ) switch architecture, in NoC to improve transmission throughput and delay between functional units. To increase performance, we use an Old Cell First (OCF) weighted matching algorithm for arbitrating contentions. We also use a simple routing scheme, X-Y routing, to route messages from source to destination. Further, the usage of the X-Y routing scheme can reduce the amount of buffer memory in the CQ router. Simulation results show that, applying the CQ switch architecture in NoC has better performance than traditional IQ-VOQ scheme in NoC.
