A platform-based de-blocking filter design with bus-interleaved architecture for H.264

Abstract

In this paper, we present an ARM platform-based architecture design for de-blocking filter in H.264. According to statistical analysis, we propose an adaptive transmission scheme to reduce the bus workload. Moreover, we develop a bus-interleaved architecture to reduce the processing latency. As compared to the state-of-the-art designs, our scheme offers 3x to 14x performance improvement. Furthermore, we have proved our design using an ARM emulation board.
