- This paper presents an Application-Specific Instruction Set Processor (ASIP) approach for implementation of H.264/AVC. The proposed ASIP has special instructions for intra prediction, deblocking filter, integer transform, etc. In addition, the proposed ASIP has hardware accelerators for inter prediction and entropy coding. Performance comparisons show a significant improvement compared with existing DSPs. The proposed hardware accelerators have small size and can support real-time video processing. Moreover, the proposed ASIP can handle various multimedia standards. The results indicate that the ASIP approach is one of promising solutions for H.264/AVC.
