This thesis presents a high performance novel VLSI architecture of a H.264 motion estimator, which can be used as a building block for real-time H.264 video compression. Full-search block matching algorithm was used in this design. Pipeline structure was developed for variable block size processing units to work in parallel. The speed at 125MHz is good for real time motion estimation with 25/sec frame rate and 640x480 resolutions. The processing speed is also independent of the threshold level of Sum of Absolute Difference (SAD), which is used to determine the size of the macro block. The architecture is implemented with Register Transfer Level VHDL codes then synthesized with Synopsys Design Compiler, using TSMC 0.25um technology. The synthesized Application Specific Integrated Circuits (ASIC's) has an area of 664um x 664um.
