Title
Speed optimization of a MPEG-4 software decoder based on ARM family cores
Abstract
MPEG-4 visual simple profile is a widely used video compression standard for mobile solutions. In general, MPEG-4 video decoder requires high computation power for its complex algorithms. It's difficult to implement MPEG-4 video decoder on hand-held devices directly. In this paper, we proposed a novel color space transform algorithm and optimized the memory access operations. Moreover, the multiperless integer IDCT is adopted to further speed up the decoder. Our optimization is based on ARM7TDMI and ARM920T, which are very desirable cores to mobile solutions for low power consumption. Experimental results show that the optimized decoder acts about 5 times faster than existing XVID MPEG-4 video decoder with small video quality degradation and supports real-time video applications.
