Abstract :
This paper describes the (field programmable gate array) FPGA implementation of two dimensional forward and inverse discrete cosine transform (2D-DCT and 2D-IDCT) using the 100 K gate ALTERA FLEX10K100 FPGA/CPLD. The architecture used in both 2D-DCT and 2D-IDCT is based on the conventional row-column decomposition method. The use of a fast algorithm and distributed arithmetic (DA) technique to implement the DCT and IDCT greatly reduces the hardware complexity
