This paper presents novel VLSI interconnection schemes that can be used to "modularize" parallel convolution circuits. Our methodology implements Toom's algorithm and is based on tensor product factorization of linear convolution into three cascaded stages. The resulting networks have very simple modular structure and highly regular topology. Additionally, the proposed networks have very small depth since only a single stage contains multipliers, while the other two stages contain adders only.
