Abstract

A C-chip VLSI decomposition of a graph G is a collection of C isomorphic disjoint subgraphs of G (the building blocks), which together contain all of G's vertices. The efficiency of such a decomposition is defined to be the fraction of edges of G that are in the building block. Motivated by the need to construct large Viterbi decoders, the authors study VLSI decompositions of deBruijn graphs. They obtain some strong necessary conditions for a graph to be a building block for a deBruijn graph, and some slightly more restrictive sufficient conditions which allow the construction of some efficient building blocks for deBruijn graphs.
