Partial Distributed Arithmetic As An Enabling Technology For Dct-based Applications On Custom Computers
Neil W. Bergmann, Yuk Ying Chung · Information Sciences, Signal Processing and their Applications · 1996
The discrete cosine transform (DCT) is a key step in many image and video-coding applications, and its efficient implementation has been extensively studied for software implementations and for custom VLSI. In this paper, we discuss how the partial distributed arithmetic algorithm can be applied to the efficient implementation of the DCT in reconfigurable logic circuits which form the core of a custom computer. Early calculations show a performance improvement of about 5 times for DCT based implementations on an FPGA compared to conventional arithmetic.
