Abstract

Discrete Cosine Transform (DCT) plays a significant role in digital signal processing, especially in various international compressing standards, such as JPEG (Joint Photographic Experts Group), MPEG4 (Moving Pictures Expert Group), and H26X. Due to its high computational complexity, fast DCT algorithms have been widely studied in recent years. This paper highlights a novel approach to calculate DCT based on first-order moments on FPGA (Field Programmable Gate Array). The proposed method is of high structural regularity, low hardware cost of PE (Processing Element) and low I/O cost. The approach is also applicable to multi-dimensional DCT and inverse DCT.
