This work presents a new VHDL design methodology and performance of a 2-D uniform finite impulse response (UCFIR) digital filter. The approach is analogous to that of the 2-D discrete cosine transform (DCT) in image processing applications. A set of 64 two-dimensional cosine basis functions are created by multiplying a horizontally oriented set of one-dimensional 8-point basis functions by a vertically oriented set of the same functions. The design was simulated, synthesized and optimized using Mentor Graphics software tools. The simulation results of the design were verified using MatLab imaging tools.
