Although the H.264 Deblocking Filter process is a relatively small piece of code in a software implementation, profile results shows it cost about a third of the total CPU time in the decoder. This work presents a high performance architecture for implementing a H.264 Deblocking Filter IP that can be used either in the decoder or in the encoder as a hardware accelerator for a processor or embedded in a full-hardware codec. A developed IP using the proposed architecture support multiple high definition processing flows in real-time.
