摘要: 介绍了大规模多DSP并行实时处理的应用需求和关键技术,并针对其中的多DSP实时网络加载技术进行了深入研究。通过对多种现有加载方案进行比较,指出各自的局限性,并最终构建了适合大规模多DSP网络的实时网络加载系统,设计了多DSP网络加载协议和网络加载同步机制,并对其性能进行评价。结合TigerSHARC(ADSP-TS101S)芯片给出了加载软件、硬件实现。最后给出该系统在工程中的实际应用。

Abstract: The application demand and key technique on large scale DSP network is reviewed, and the real-time net-booting scheme is substantially analyzed. Having examined several published booting scheme, we find it necessary to build a real-time net-booting system to meet the net-booting requirement of the large scale DSP network, since the schemes presented are not suitable for such condition. This paper constructs a real-time net-booting system, designs the net-booting protocol and the synchronization scheme, then provides system performance assessment. A hardware and software implementation and a practical application via TigerSHARC (ADSP-TS101) with it.
