Parallelizing H.264 and AES Collectively

초록

Many applications can be parallelized by using multicore platforms. We propose a load-balancing technique for parallelizing a whole application, whose first module (H. 264) has data independency and whose second module (AES) has data dependency. Instead of distributing the first module symmetrically over the multi-core platform, we distribute the data-independent workload asymmetrically in order to start the data-dependent workload as early as possible. Based on the experimental results with a compression/ encryption application, we confirm that the asymmetric load balancing can provide better performance than the typical symmetric load balancing.
