Abstract :
This work presents the HP422-MoCHA, the first published hardware architecture that implements a full compliant H.264/AVC motion compensator for high profile 4:2:2. The hardware is composed by three main modules: Motion Vector Predictor, Memory Access and Sample Interpolator. The designed architecture was described in VHDL and mapped to a Xilinx Virtex-II PRO FPGA. This architecture reaches the throughput to decode HDTV Level 4 (1080p) @ 30fps.
