This paper presents a high-throughput and low-power integrated HEVC direct/inverse quantization hardware design. The main focus of this design is to allow the evaluation of multiple coding modes during the residual encoding process of the HEVC for real-time Ultra-High Definition (UHD) video processing. The ASIC synthesis results, for a Nangate 45nm standard cell library, presented a maximum operational frequency of 1679.51MHz and a processing rate of 53.74 Gsps (giga samples per second). This throughput allows processing of real-time up to 72 coding modes for UHD 4K@60fps or up to nine coding modes for the UHD 8K@120fps while dissipating 369.37mW.
