Decoder Hardware Architecture for HEVC

This chapter provides an overview of the design challenges faced in the implementation of hardware HEVC decoders. These challenges can be attributed to the larger and diverse coding block sizes and transform sizes, the larger interpolation filter for motion compensation, the increased number of steps in intra prediction and the introduction of a new in-loop filter. Several solutions to address these implementation challenges are discussed. As a reference, results for an HEVC decoder test chip are also presented.
