Paper 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.
