HEVC 복호화기를 위한 효과적인 병렬화 설계

In this paper, we propose parallelization method for HEVC decoder software. The proposed HEVC decoder is partitioned into three modules according to the parallel characteristic of each module. To achieve maximum parallel performance, we use task level parallelism (TLP) between entropy decoding and pixel decoding modules. Furthermore, we apply largest coding unit (LCU) based 2D wavefront for pixel decoding and data level parallelism (DLP) for in-loop filters. Experimental results show that the proposed HEVC decoder achieved decoding time reduction up to 3.03x compared to single core-based HM reference software.
