Fast H.264 intra prediction for network video processing

Abstract

This letter proposes a fast parallel and deeply pipelined architecture for realtime H.264 intra 4×4 prediction capable of handling up to 32 High Definition video streams (1920 × 1080 @ 30 fps) simultaneously, while offering high flexibility and consuming only a fraction of resources available on modern FPGA's. The design has been validated on target using a state of the art Altera Stratix IV FPGA.
