Network-on-Chip (NoC) architectures provide a good way of realizing efficient interconnections and largely alleviate the limitations of bus-based solutions. NoC has emerged as a solution to problems exhibited by the shared bus communication approach in System-On-Chip (SoC) implementations including lack of scalability, clock skew, lack of support for concurrent communication and power consumption. The communication requirement of this paradigm is affected by architecture parameters such as topology, routing, buffer size etc. In this paper, we propose advanced optimization techniques for OASIS NoC, a NoC we previously designed. We describe the architecture and the novel optimization techniques in details. Hardware complexity and preliminary performance results are also given.
