Abstract

The paper discusses an implementation of MPEG-4 simple profile video real-time encoder based on TMS320DM642.For the real-time requirement,after analyzing the hardware architecture and instruction characteristics of DM642,we present the implementation of video encoder and optimization methods.We achieve real-time encoder of CIF(352×288) pictures,which demonstrates that the high performance of DM642 can meet the requirement of video real-time encoder.
