通过对通用编码器性能的研究分析,本文提出了一种新的编码器设计方案。本文采用了美国模拟器件公司专为通信和互联网而设计的第四代DSP芯片Blackfin533;采用了基于内容压缩的高压缩比协议MPEG-4协议;并提出了一系列优化编码器的方案。实验表明这一编码器具备了通用编码器所不具备的优点,如功耗低、价格低、体积小、便于升级等。 Through the research on the performance of universal encoder, this paper presents a new encoder design. In this paper, Blackfin533, the fourth generation DSP chip specially designed by American Analog Devices for communication and the Internet, is adopted. MPEG-4 protocol based on content compression is adopted, and a series of schemes for optimizing the encoder are proposed. Experiments show that the encoder has a common encoder does not have the advantages, such as low power consumption, low price, small size, easy to upgrade.
