In this paper, we present an efficient hardware architecture for real-time implementation of quarter-pixel accurate variable block size motion estimation for H.264 / MPEG4 Part 10 video coding. The proposed hardware performs quarter-pixel interpolation dynamically, i.e. only the quarter pixels necessary for performing quarter-pixel accurate search at the location pointed by the half-pixel motion vector are calculated. This reduces the amount of computation performed for quarter-pixel interpolation, and therefore reduces the power consumption of the quarter-pixel accurate motion estimation hardware. This hardware is designed to be used as part of a complete H. 264 video coding system for portable applications. The proposed hardware architecture is implemented in Verilog HDL. The Verilog RTL code is verified to work at 60 MHz in a Xilinx Virtex IIFPGA. The FPGA implementation can process 34 VGA frames (640x480) per second.
