This paper presents a high efficiency video encoder implementation (HEVC) on two different Texas Instruments (Tl) platforms: the BeagleBoard-xM based on ARM processor and the TMS320C6678 DSP. The new features of these processors such as multicore architecture, high frequency processor and low power consumption motivate researchers to develop an embedded HEVC video encoder which could be exploited in several multimedia applications such as High Definition (HD)TV, smart cameras, HD video conference, Ultra HD video surveillance systems. Different operating systems (OS) with different compilers are tested in order to obtain an optimized HEVC encoder implementation. Experimental results show that HEVC encoder DSP-based solution using SYS BlOS real time OS allows saving up to 62% of encoding time compared to Linux-c6x OS with the same DSP and about 71% of encoding time compared to BeagleBoard-based solution without inducing any performance degradation in terms of video quality or bitrate.
