The High Efficiency Video Coding (HEVC) standard devised with the aim of providing double compression compared to its predecessors H.264 and MPEG-4 standards. This is primarily due to the variable sizes of blocks, called Coded Tree Unit (CTU) structure and numerous new prediction modes. However, this improved compression efficiency accompanies high computational complexity, which is primarily due to the recursive nature of the Coding Tree Unit structure and complex Rate-Distortion (RD) Optimization of Prediction Units (PU).
