A single chip processor architecture for video rate two-dimensional digital filtering

A VLSI single-chip processor architecture for real-time 2-D digital signal-processing applications is presented. This architecture extends the concept of using a single processing unit to the use of multiple processing units. The advantage of this architecture is that the complexity and the number of computations per unit of input does not increase as the size of 2-D input data increases. Thus, it can process a very large amount of 2-D data efficiently and nearly in real-time. The processor architecture yields a simple and efficient system configuration. It is especially suited for a large class of digital signal-processing algorithms classified as discrete linear shift-invariant systems
