Abstract: Discrete Cosine Transform (DCT) is an important transform of particular interest in still image compression and compression of individual video frames, while multidimensional DCT is mostly used for compression of video streams and volume spaces. An FPGA implementation of a Polynomial Transform DCT (PTDCT) algorithm, recently proposed by Zeng et al. [10], is presented. The regularity of Zeng’s algorithm and careful operation scheduling have resulted in a very efficient implementation of a two-dimensional DCT in Xilinx Virtex-II FPGA in the terms of logic requirements.
