Abstract
This paper presents the architecture and design of intra prediction circuit for H.264 decoder. There are a total of 17 operational modes in the intra prediction of H.264- nine modes for a luma $4\times4$ block, four modes for a luma $16\times16$ block and four modes for a chroma $8\times8$ block. We extracted common operations included in all prediction modes and defined the common operations unit to perform those operations. The proposed circuit architecture sharing this unit in all prediction modes is systematic from the design point of view and efficient in terms of circuit size.
