A Novel FPGA-based H.264/AVC Intra Prediction
Guoyan Ren, Jianjun Li · Fuzzy Information and Engineering · 2011
The advanced video compression standard H.264/AVC adopts Rate Distortion Optimization to enhance coding efficiency at the cost of a very high computational complexity. Intra Prediction part is the major processing bottleneck considering total time and power consumption. We therefore propose an efficient parallel processing structure for H.264/AVC 4 × 4 intra prediction. Unlike generic architectures utilizing serial processing with increased time and power consumption, a new processing order is introduced to reduce data dependencies between consecutively executed blocks within H.264/AVC intra prediction. Our experimental results show that the parallel execution of these blocks saves power consumption by up to 22.8% with slight increase in bit rate.
