摘　　要：设计一种基于以太网技术的数字信号处理器(DSP)阵列系统,采用以太网交换芯片作为交换中枢,每个DSP有独立的MAC地址和IP地址,通过以太网交换芯片交互数据。硬件架构可根据需要随意扩展DSP的个数,DSP软件实现了链路检测方法,保证了通信的可靠性。A kind of DSP array system based on Ethernet is designed. Ethernet exchange chip is the exchange center of the system. Each DSP has a separate MAC address and IP address. They exchange data through Ethernet. The system can be expanded as flexible as possible. The software of DSP realizes the method of link detection that ensures the reliability of communication.
