Recent researches on parallelization of H.264 video decoders focused on fine-grain methods. These works led to designs having very short latencies and good memory usage. However, they could not reach the scalability of Group of Pictures (GOP) level approaches although assuming a well-designed entropy decoder which can feed the increasing number of parallel working cores. We would like to introduce...
Performance evaluation is key to the optimization of computer applications on multicore systems. While many techniques and profiling tools are available for measuring performance on homogeneous multicore platforms, most of them depend on the hardware support from the vendors. For developing applications on heterogeneous multicore systems, very few analysis tools exist to help the developers. This...
Executing functional components in pipeline on heterogeneous multi-core platforms can greatly improve the parallelism but require great amount of data communication among processes and threads. Our studies showed that existing inter-process/thread communication protocols consist of many unnecessary memory copies and prolong the execution of the applications on heterogeneous multi-core platforms. NTU...
