In recent times, it has become possible to parallelize many multimedia applications using multicore platforms such as CPUs and GPUs. In this paper, we propose a parallel processing approach for a multimedia application by using both the CPU and GPU. Instead of distributing the parallelizable workload to either the CPU or GPU, we distribute the workload simultaneously to both by using OpenCL. Based on our experimental results, using both the CPU and GPU, we confirm that the proposed parallel processing approach provides better performance than typical parallel processing approaches on account of maximal utilization of the given resources.
