| In recent times, a variety of novel applications have emerged for real-time VLSI multi-dimensional digital filters, of which many draw upon broadband plane-wave filtering for array-based beam-forming or, the processing of image sequences in video signals. This thesis reports on recent advances in 2D/3D FPGA recursive digital filters, suitable for sampled sensor-array based real-time signal processing on a single CMOS integrated-circuit.; Two architectures are hitherto proposed. These employ synchronous and asynchronous array sampling methods, and thereby achieve different objectives as per the particular application. The architectures, classified as distributed-parallel-processor and scanned-array, are designed, simulated and demonstrated using 2D and 3D example design implementations on a single Xilinx FPGA device. |
