As 3D System-on-Chips (SoCs) come ever closer to becoming the standard for high performance ICs, 3D Networks-on-Chips (NoCs) have emerged as a key component in meeting performance constraints and ensuring power-efficiency. Among the proposed 3D router architectures, dimensionally-decomposed routers are widely accepted as an efficient solution to deal with the increased port count and the accompanying exponential power and area increases. All decompositions proposed thus far have however been dimensionally static, that is, they have set in stone a particular bias among the three dimensions.
