Abstract
A system for performing finite input response filtering. The system includes an array of random access memories (RAMs) for storing at least one two-dimensional (2D) block of pixel data. The pixel data is stored such that one of each type of column or row from the 2D block of pixel data is stored per RAM. A control block provides address translation between the 2D block of pixel data and corresponding addresses in the array of RAMs. An input crossbar writes pixel data to the array of RAMs as directed by the control block. An output crossbar simultaneously reads pixel data from each of the array of RAMs and passes the data to an appropriate replicated data path, as directed by the control block. A single instruction multiple data path block includes a plurality of replicated data paths for simultaneously performing the FIR filtering, as directed by the control block.
