Efficient implementation of MPEG-4 video encoder on RISC core

MPEG-4 simple profile video is being used as the video compression standard in mobile video communications. MPEG-4 video requires more computational power because of its high complexity. Currently, RISC cores are widely used in mobile applications because of their low power consumption. Design of fully standard-complaint MPEG-4 video encoder with real time performance on a RISC processor for embedded applications entails optimizations at all levels to the maximum extent possible. This paper describes in detail about the implementation of MPEG-4 simple profile video encoder on efficient RISC processor core requiring 50 Mega Cycles to encode QCIF resolution video at 15 frames per second with minimum processing power and memory requirements.
