This paper describes an efficient architecture enhancement for video codec on a new-generation, general-purpose digital signal processor (DSP) core called SPXK5 developed for handheld devices. With high performance features of SPXK5's base architecture, an MPEG-4 video codec can be implemented efficiently. In addition, only a few SIMD type instructions effectively accelerate MPEG-4 video codec implementation by 20% with only 2.5% hardware increase. By reducing cycle count, the DSP's power consumption can be reduced. Both video and speech codec for 3G mobile service at 384kbps can be realized with a power consumption of less than 50mW.
