In this paper, we study the hardware requirement for 2-D image convolution on an electro-optical model. We identify the basic components of an Optical model of parallel computation using optical interconnects and their relationship with well known VLSI grid model from a computational perspective. We show a lower bound of W(nw) on the volume requirement of any electro-optical chip for 2-D image convolution using a w x w window and a n x n image. This bound also applies to the area requirement of a VLSI chip. Designs available in the literature for computing the 2-D image convolution are compared with respect to their hardware requirement.
