Abstract
This paper presents a straightforward multiplier-less approximation of the forward and inverse Discrete Cosine Transform (DCT) with low complexity and high accuracy. The implementation, design methodology, complexity and performance tradeoffs are discussed. Particular, the proposed IDCT implementations, in spite of simplicity, comply with and can reach far beyond the MPEG IDCT accuracy specification ISO/IEC 23002-1, and also reduce drift favorably compared to other existing IDCT implementations.
