The Application And Implement Of H.264 Based On The DSP In The Embedded Linux

On the basis of deeply study of H.264 and Blackfin DSP, this paper realize the H.264 video codec standard transplanting and optimizing on the Blackfin DSP.H.264 video codec standard is called the next generation standard. This paper presents the H.264 codec principle,intraframe and interframe prediction, interger transformation,quantizaion,CAVLC entropy encoding. The Blackfin DSP is the new generation embedded processor,which is developed by ADI with Intel,the first generation fourth generation of DSP product,using the new brand MSA construction,supporting the embedded operating system—uClinux,for example.The paper presents the cross—compiling the uClinux operation system,and then running the H.264 video codec standard program JM. In the end ,it realizes the optimization of JM program on the DSP.
