Title: The Optimization Implementation of H.264 Video Encoder Based on General DSP
Abstract: Compared with MPEG-4 and other previous standards, H.264 standard has achieved great break through in coding performance. To meet the requirement of embedded video encoder in various scenarios, an H.264 real-time encoder based on TI TMS320C 6455 is presented in this paper. According to the characteristics of the structure, resources and instruction of the selected DSP, a lot of work have been done at the structure level, the algorithm level and the code level to get a high performance encoder. The experimental results demonstrate that, for the video sequences with 720 times 576 format, the H.264 encoder optimized can achieve the encoding speed of more than 25 frames per second, which can meet the real-time requirements of the applications.
