A Digital IF Pre-processing Platform Scheme Based on High-speed Serial Bus

随着语音数字输入、图像处理和其它需要大数据量实时处理等需求的出现,高端系统需要处理的数据量急剧增加,串行总线结构的优势将日益明显。本文在介绍高速总线技术及发展趋势的基础上,提出了一种基于高速串行总线的数字中频预处理平台的设计方案,详细介绍了工作原理、主要器件,以及高速串行总线的具体实现方案。经过工程应用验证,该方案性能指标良好,且可动态配置,控制结构简单、可靠性高、扩展性好、通用性强,具有良好的推广应用前景。

With the progress of real-time signal processing for audio, image and other digital applications. Lot of digital information needs to be dealt in many communication systems. Serial bus has many advantages in these scenarios. A digital IF pre-processing scheme is proposed by using high-speed serial bus in this paper. The scheme is based on software defined radio technology and is very suit for high speed communication systems. The design has already been successfully implemented in some projects and has well performance. The application indicate that the proposed scheme have the characters of simple controlling structure, high reliability and good expansibility.
