Abstract:

This paper explains how the Open Reconfigurable Video Coding CAL Actor Language compiler framework (Orcc) has been used, along with the Open Multi-Processing (OpenMP) API, to implement an HEVC video decoder based on multicore DSP technology. Currently, two DSP cores have been used, though the technique may be applied to the development of N-core based implementations. The two core based decoder presented in this paper outperforms a single core implementation by 70%.
