Design of Transform and Quantization Circuit for Multi-Standard Integrated Video Decoder

This paper presents a new method to design the circuit that can perform the inverse transform and inverse quantization operations for three popular video compression standards WMV9, MPEG-4 and H.264. We introduced a delta coefficient matrix and implemented the integrated inverse transform circuit based on the proposed idea. We designed the integrated inverse quantization circuit using a shared multiplier. The entire circuit was verified on the SoC platform board, synthesized into a gate-level circuit using 130nm standard cell library and showed its efficiency in terms of the circuit size.
