Abstract

This paper presents a novel error-free (infinite-precision) algorithm for the fast implementation of H.264 like 4×4 DCT/Quan_IQuan/IDCT based on algebraic integer-encoding scheme. This encoding technique eliminates the requirement to approximate the transform matrix elements by obtaining their exact representation. The proposed algorithm has regular structure and simulation results shows reducing computing complexity with enhanced quality simultaneously. Furthermore it is multiplication free and suitable for the high speed implementation with a fully pipelined systolic architecture.
