Deadlock Free Routing in Irregular Interconnection Networks for Complex SoCs

Networks-on-Chip (NoC) is recently proposed as an alternative communication infrastructure/Interconnection Network for address the high communication demands of the complex futuristic SoCs. Most researchers advocate the use of traditional regular networks like meshes as architectural templates which gained a high popularity in general-purpose parallel computing. However, most SoC platforms are special-purpose tailored to the domain-specific requirements of their application. They are usually built from a large diversity of heterogeneous components which communicate in a very specific, mostly irregular way. In such systems the size and nature of cores may vary quite widely making the topology irregular.
