As an important communication infrastructure, the data transmission efficiency of Network-on-Chip (NoC) plays a key role in improving the performance of multi-core systems. A packet and circuit switching mechanism based adaptive transmission network (PCSAT_NET), supporting X-Y routing and Retrograde-Turn routing strategies, which is suitable for mass data transmission is proposed here. It also adopts targeted optimization measures for mass data transmission, including keep-alive and adaptive transmission mechanism. The goal of this architecture is to achieve higher transmission efficiency in a congested data network. Therefore, we deployed a multi-core system based on this network, and experimental results show that compared with the traditional packet and circuit switching mechanism based network, PCSAT_NET could reduce the overall run time by at least 23% when the data network is severely congested and each task competes for computing resources.
