Design of an intra predictor with data reuse for high-profile H.264 applications

This paper presents a high-profile intra predictior for H.264 video decoder. To alleviate the starved bandwidth of intra compensation in high-definition video, we reuse the neighboring pixels and optimize the buffer size and access latency. In particular, a dedicated pixel buffer reuses neighboring pixel for realizing MB-adaptive frame-field (MBAFF) decoding in intra compensation. Moreover, a base-mode predictor is explored to optimize the area efficiency for reference sample filtering process (RSFP) in intra 8×8 modes. Simulation results show that the proposed data-reused intra prediction module requires 14K logic gates and 688 bits SRAM, and operates on 100MHz frequency for realizing 1080HD video playback at 30fps.
