On speed optimization of MPEG-4 decoder for real-time multimedia applications
In this paper, we present several speed optimizing techniques in our MPEG-4 video decoder for real-time multimedia applications. Accessor functions and a simple data structure are used. The use of pointers is minimized. Fast algorithms and fixed-point arithmetic are applied whenever possible. Memory accesses are kept to the minimum. Our results show that our software can decode and display MPEG-4 QCIF videos about eight times faster than the existing MoMuSys decoder.
