DANoC: A dynamic adaptive Network on Chip architecture

Network-on-Chip has became a mainstream technology to solve the communication problems in Multi Processor SoC (MPSoC); and it has a greatly impact on system´s performance, area and power consumption. In order to improve the performance of Network-on-Chip to fulfill the requirements of the MPSoC, this paper presents a dynamic adaptive NoC (DANoC) architecture, which can achieve the topology dynamic adaptation at run time. There are many features of DANoC, such as: the topology is simple and regular; the architecture is easy to extend in different network scales; the network traffic load is balanced. DANoC and Mesh have been verified under different network scales, injection rates and traffic patterns. The experimental results show that DANoC could effectively reduce latency and improve throughput, which is a simple and efficient Network-on-Chip.
