The efficient real-time spatial domain 2-D IIR and FIR digital filter implementation

Presents an efficient hardware implementation of spatial domain two-dimensional IIR and FIR filters. The authors use a state space representation to achieve efficient algorithms and then use a common computational primitive to optimize the hardware implementation. They present a multiprocessor implementation for a real-time or near real-time two-dimensional linear system with a raster scan input. The multiprocessor system has a simple control scheme, a simple interconnection network, a very high efficiency, and low data transfers
