A survey on the hardware realization of 2-D state space filtering

Hardware realization of 2-D state space filtering is a big problem of present scenario. In the decade of seventy, the theoretical realizations of 2-D linear state-space models were reported by various researchers. Among these models, the general model is suitable for state space filtering and hardware realization. The beauty of general model SSF is that, it may be transform either in Fornasini-Marchesini (FM) first or second model after slightly modification in hardware. In this article, we present a brief overview of the key developments in hardware realization of the state apace filtering algorithms and architectures.
