Abstract
A method by which a two-dimensional array of logic elements may be interconnected such that they may be modeled as a three-dimensional array, while minimizing routing crossings. The result is an arrangement that is highly efficient for implementation in a silicon die. The preferred model may be extended to a three-dimensional torus where opposing faces of the array are considered to be adjacent. Routing flexibility is increased by increasing local interconnect while minimizing interconnect crossover.
