A highly-modular pipelined VLSI architecture for 2-D FIR digital filters

A highly-modular pipelined VLSI architecture for two-dimensional (2-D) finite impulse response (FIR) digital filters is presented. This approach decomposes the 2-D discrete convolutions into pipelined summations of parallel 1-D discrete convolutions, so that modular structure is obtained. The advantages of this architecture are: (i) regular structure with high modularity, (ii) fully pipelined operation with maximum utilization of the hardware resources, (iii) the real-time processing ability with low system latency
