Abstract
The increasing demand on the use of multimedia video contents drives more mobile embedded systems to incorporate H.264/AVC decoding capability. An H.264/AVC decoder often requires high computation bandwidth during its decoding phase. Depending upon processor computation capability and multimedia contents complexity, the decoder can be implemented either in hardware or software. However, without a thorough analysis on the Performance and resource requirements, it is difficult to choose a cost-effective methodology of implementing this codec. This paper presents both hardware and software implementation of H.264/AVC decoding subsystem in mobile embedded systems, and quantitatively analyses the performance and resource requirements. It also shows the methodology to identify performance bottleneck in Linux-based mobile embedded systems, which is in turn used to select feasible and efficient implementation methodology.
