초록

This paper presents an efficient architecture of unified transform and quantization circuit for H.264/JPEG CODEC. The proposed unified transform circuit shares adders required for all transform operations. The proposed unified quantization circuit uses four multipliers. Our transform circuit and quantization circuit consist of 33,711 gates and 9,650 gates respectively. The maximum operating frequency is 100MHz with 130nm standard cells.
