Abstract： With the deep development of integrated circuit technology to the nanoscale, network-on-chip (NoC) has received extensive attention as a key technology to solve the communication bottleneck in multi-core systems. Based on the latest research results, this paper discusses several aspects of key issues affecting the development of NoC, including typical technologies and recent progress in topology, routing algorithms, switching mechanisms, and quality of service, etc. The study shows that some current emerging technologies significantly enhance the performance of NoC, such as lowering the communication latency, improving throughput, optimizing the power control, and increasing the resource utilization rate. Nevertheless, they still face many challenges such as high integration difficulty and difficult traffic management. Finally, this paper summarizes the existing problems of NoC technology and discusses the future development trend.
