This paper proposes a history-based tiling algorithm aiming at the increase of speedup when using Tiles. The algorithm is composed of two independent steps that use workload history information to define the vertical and horizontal boundaries of the Tiles. The workload distribution of previous frames are used as reference to perform the tiling of the current frame exploiting the temporal similarity between neighboring frames. Experimental results show that the proposed algorithm outperforms the speedup when compared to uniform tiling by 6.85% on average for tested sequences, besides, there is no significant complexity increase and similar coding efficiency results. When compared to related works the proposed solution also presents better speedup results.
