Joint collaborative team on video coding (JCT-VC) recently developed a new international video compression standard called High Efficiency Video Coding (HEVC). HEVC has 50% better compression efficiency than previous H.264 video compression standard. HEVC achieves this video compression efficiency by significantly increasing the computational complexity. Motion estimation is the most computationally complex part of video encoders. Integer motion estimation and fractional motion estimation account for 70% of the computational complexity of an HEVC video encoder. High-level synthesis (HLS) tools are started to be successfully used for FPGA implementations of digital signal processing algorithms. They significantly decrease design and verification time. Therefore, in this thesis, we proposed the first FPGA implementation of HEVC full search motion estimation using Vivado HLS. Then, we proposed the first FPGA implementations of two fast search (diamond search and TZ search) algorithms using Vivado HLS. Finally, we proposed the first FPGA implementations of HEVC fractional interpolation and motion estimation using Vivado HLS. We used several HLS optimization directives to increase performance and decrease area of these FPGA implementations.
