The current trend of digital convergence leads to the need of the video encoder/decoder (codec) that should support multiple\r\nvideo standards on a single platform as it is expensive to use dedicated video codec chip for each standard. The paper presents a\r\nhigh performance circuit shared architecture that can perform the quantization of five popular video codecs such as H.264/AVC,\r\nAVS, VC-1, MPEG-2/4, and JPEG. The proposed quantizer architecture is completely division-free as the division operation is\r\nreplaced by shift and addition operations for all the standards. The design is implemented on FPGA and later synthesized in\r\nCMOS 0.18 �µm technology. The results show that the proposed design satisfies the requirement of all five codecs with a maximum\r\ndecoding capability of 60 fps at 187MHz on Xilinx FPGA platform for 1080 p HD video.
