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.
