Abstract :
Several linear-array processors are developed for two-dimensional (2-D) finite impulse response (FIR) and infinite impulse response (IIR) digital filters. The input signal is processed in a column-by-column scheme, thus an extremely high processing speed is reached. The speed is high enough for real-time image processing and computer vision. The array processors possess high regularity, simple data-communication schemes, simple control, and data-driven format. The number of processing elements (PEs) can be changed according to applications. The array processor for IIR filtering is developed by combining the uses of the new array processors for 2-D FIR filtering and existing array processors for 1-D IIR filtering
