Multicore and Mesh Network-based Parallel Performance Evaluation using Intra Prediction Algorithms

So far, many parallel algorithms have been developed under the assumption that a high performance multicore processor uses a bus for inter-core communications. However, this assumption begins to change as the number of processing cores is increased and thus, higher connectivity among cores is required. So, in this paper, three HEVC intra prediction algorithms are ported into a mesh network-based multicore system by using a wavefront-style parallelization. By analyzing parallel performance, this paper shows that UDIP best fits in the mesh network-based multicore system (almost 2 times faster than other algorithms).
