On-chip communication architectures can have a great influence on the speed and area of multi-core processor (MCP) designs. A new chip design paradigm called Network-on-Chip (NOC) offers a promising interconnection architectural choice for future MCP. A new on-chip interconnection network named Triple-based Hierarchical Interconnection Network (THIN) is proposed that aims to decrease the node degree, reduce the links and shorten the diameter. The topology of THIN is very simple and it has obviously hierarchical, symmetric and scalable characteristic. THIN applies the hierarchical address-encoding scheme that can make the design of routing algorithm simple and efficient. The network properties are studied and compared with 2-D mesh. The results show that THIN is a better candidate for constructing the NOC than 2-D mesh, when there are not too many cores.
