Abstract
In this thesis, we propose and implement a novel high speed switch named NTU-IV switch which is based on multi-plane cross-bar switch fabric. This switch has low complexity and the ability to handle variable length packets asynchronously. In addition, our switch supports both unicast and multicast. The concept of modular design is embedded into the architecture of the NTU-IV Switch. Therefore the NTU-IV Switch has great scalability in port count and line-rate. Simulation results show that this switching architecture can eliminate head-of-line blocking (HOL blocking) effect and also emulate the performance of output queue (OQ) switch without the need of complicated contention resolution algorithm and arbiter. We use the 0.18 μm cell – library design flow to implement a 16x16 NTU-IV Switch prototype with a total switching capacity of 160 Gb/s. Our design flow includes behavior level (Verilog code), synthesis, place and route. It is shown that the switch has low delay and almost 100% throughput under uniform traffic condition.
