Design of a High-Performance Switch for Circuit-Switched On-Chip Networks
Chia‐Ming Wu, Hsin-Chou Chi · 2005
System-on-a-chip (SoC) designs provide designers to integrate dozens of heterogeneous IP blocks together by a dedicated interconnect network. The major problems in the ultra deep sub-micron technology SoC design arise from the interconnection networks, such as non-scalable global wire delay, failure to achieve global synchronization, and errors due to signal integrity issues. These problems might be mitigated by the network-on-chip (NoC) approach based on regular on-chip communication networks. In this paper, the authors propose the pre-scheduled circuit-switched network for NoC architectures. The authors have designed the switch supporting the network. Such architectures based on circuit switching with efficient buffer management can achieve guaranteed transmission latencies
