Research on congestion perception and control of network on chip

Network on a chip(NOC) is a new kind of communication method on a chip, which is evolved from system on a chip(SOC), learning from computer network. It is an important component of the multi-core technology. The network on a chip provides a new way to communicate, and it performs better than the original system on a chip based on bus. As the size of system on a chip expanded, the number of nodes in the system increases complexity, the traditional bus-type data transmission has encountered a performance bottleneck. In order to obtain a high throughput, low computing latency system on a chip, this paper proposes a new congestion sensing and control methods: a congestion controlling dynamic routing method based on dynamic routing table.
