应用高性能DSP作为数据处理的主节点,借助多DSP并行处理技术设计大规模实时处理系统已成为发展趋势。该文介绍了多DSP并行处理技术,研究了一种基于网络交换结构的多DSP系统构成及并行处理单元DSP间的互联技术,针对多DSP系统的调试与开发给出了一种解决方案。该项技术拓展了DSP的网络接口能力,实现了DSP技术与网络技术的完美结合,推动了网络化测控技术的发展。
Application of high-performance DSP as the main data processing node, with multi-DSP parallel processing technology to design large-scale real-time processing system has become a trend. This paper introduces multi-DSP parallel processing technology, studies a multi-DSP system structure based on network switch fabric and interconnects between parallel processing units (DSPs), and provides a solution to the debugging and development of multi-DSP systems. This technology has expanded the network interface ability of DSP, has realized the perfect combination of DSP technology and network technology, has promoted the development of networked measurement and control technology.
