**4. The proposed fast configuration**

Several fast decision mode algorithms are in this effort aiming to speed up the ME process. Firstly, diamond search pattern is utilized to decrease the encoder computational complexity. Some configurations are also set, such as the early CU termination (ECU), the early skip detection (ESD), and the coded block flag (CBF) in which fast decision mode algorithms are adopted in HEVC video coding. These proposed fast algorithms were given bellow.

(advanced motion vector prediction called AMVP and merge mode). The DMV and CBF are checked when the minimum RD cost is induced by the mode selection. When CBF is equivalent to zero and the best mode inter 2 N 2 N DMV is equal to (0, 0), the skip mode is the best mode of current CU. Consequently, the residual
