A multiprocessor architecture for two-dimensional digital filters
In this paper, a generic computational primitive is developed for the implementation of any arbitrary order one-dimensional or two-dimensional FIR or IIR digital filter. This computational primitive can form the basis for a single chip processor for one-dimensional and two-dimensional digital signal processing. A multiprocessor architecture for real-time implementation of spatial domain filters is developed with each processing unit in the network implementing the computational primitive. This multiprocessor system has a simple control scheme, a simple interconnection network, a very high efficiency, and low data transfers and storage requirements. Thus, it avoids the bottlenecks associated with traditional parallel computers and multiprocessor systems.
