| Summary: | 碩士 === 國立雲林科技大學 === 通訊工程研究所碩士班 === 99 === The goal of this paper is to port the H.264 reference C code "T264" developed by Chinese Video Encoding Freeware Organization to Texas Instruments(TI) TMS320DM642 DSP development platform.Since H.264 encoder is high in computational complexity, the main challenge is to speed up encoding process for real-time (30 frames per second QCIF) video compression. In order to achieve this goal, we adjust parameters provided by TI Code Composer Studio''s (CCS) for option-level optimization, we also rewrite some functions in C code to linear assembly code and explore possible parallel processing. The experimental results show an average savings about 71% of computational complexity.
