In this paper, we study a nanoโscale highly parallel computing architecture for image processing: a reconfigurable mesh that is interconnected with ferromagnetic spinโwave buses. In this architecture, information is encoded into the phase of the spinโwave, and interommunications are performed without any charge transfer. This spinโwave reconfigurable mesh, while requiring the same number of switches as standard reconfigurable mesh, is capable of simultaneously transmitting multiple waves on each of the spinโwave paths using different frequencies. Moreover, in this architecture, the superposition characteristic of spinโwaves allows concurrent writes if all the requesting processors write a โ1โ. Employing these parallel features, we present three constant time image processing applications for this architecture. We show that given an N^1/2^ ร N^1/2^ image, using a N ร N spinโwave reconfigurable mesh, in constant time, all figures. can be labelled, and the nearest neighbour, and the convex hull of a single figure can be found.
