Decentralized Control of Switching Elements in the Intra-Chip Network-on-Chip Routers

We propose a novel switching element with decentralized control for communication systems. In the paper for convenience we have proposed some fragments of the description of a switching element in the VHDL hardware description language. Such switching elements can become part of the switch fabric of NoC technology routers. In our opinion, the decentralization of the switching elements control provides the following advantages: distributed arbitration rather than centralized; flexible balancing of the information traffic due to the shared use of network buffers for various routes; packet route diversity for the same sources and receivers; simplification of port controllers improved scalability of the intra-chip communication system. In addition, we guess that NoC communications can find application in IoT technology, because it combine routing functions with information processing functions.
