摘要
在ADI公司的ADSP-BF561多媒体芯片上完成了H.264编解码标准的实现。首先简要介绍了H.264标准的技术特点和ADSP-BF561平台及其编解码库,然后再结合该结构详细的阐述了一系列的设计和优化策略,编解码器在达到实时通信的要求上进一步提高性能。最后针对不同环境的图像系列对系统性能和资源消耗进行了测试。
In this paper,the H.264 video codec standard is successfully implemented on the ADSP-BF561 multimedia platform.First,it presents a brief introduction of the performance and characteristics of the H.264 codec standard,the ADSP-BF561 hardware platform and its H.264 codec library.After that,a series of design and optimization strategies has been used to achieve real-time video codec on this platform and further performance improvement.Finally,the YUV test sequences with different environments were tested to get system performance and MIPS consumption.
