    This paper analyzes the complexity of the HEVC video decoder being developed by the JCT-VC community. The HEVC reference decoder HM 3.1 is profiled with Intel VTune on Intel Core 2 Duo processor. The analysis covers both Low Complexity (LC) and High Efficiency (HE) settings for resolutions varying from WQVGA (416 × 240 pixels) up to 1600p (2560 × 1600 pixels). The yielded cycle-accurate results are compared with the respective results of H.264/AVC Baseline Profile (BP) and High Profile (HiP) reference decoders. HEVC offers significant improvement in compression efficiency over H.264/AVC: the average BD-rate saving of LC is around 51% over BP whereas the BD-rate gain of HE is around 45% over HiP. However, the average decoding complexities of LC and HE increase by 61% and 87% over BP and HiP, respectively. In LC, the most complex functions are motion compensation (MC) and loop filtering (LF) that account on average for 50% and 14% of the decoder complexity. The decoding complexity of HE configuration is on average 42% higher than that of the LC configuration. Majority of the difference is caused by extra LF stages. In HE, the complexities of MC and LF are 37% and 32%, respectively. In practice, a standard 3 GHz dual core processor is expected to be able to decode 1080p HEVC content in real-time.
