This paper presents a Fast Center Search Algorithm (FCSA) and its hardware implementation design of integer Motion Estimation for High Efficiency Video Coding (HEVC). FCSA achieves average time saving ratio up to 40% for HD video sequences with respect to full search, with insignificant loss in terms of PSNR performance and bit rate. The proposed hardware implementation shows that it meets the requirements of 30 4K frame per second with ±16 search window at 550 MHz. The prototyped architecture utilizes 8% of the LUTs and 4% of the slice registers in Xilinx Virtex-6 XC6VLX-550T FPGA
