声纳信号处理中UDP协议数据传输研究与设计

为了在声纳系统中通过以太网口进行大批量、高速率的数据传输处理,在FPGA中硬件实现了嵌入式UDP协议栈,完成了架构设计、软件仿真验证及硬件实现。用FPGA硬件实现UDP协议栈,加速了网络数据处理能力,使信号传输速率达到了80MB/s,实现了千兆级通信,很好地提高了声纳系统中数据传输速率和系统性能。同时,用FPGA硬件实现UDP协议,栈减小了PCB版图面积和布局布线复杂度,提高了开发效率,有效地降低了开发成本。

Data transmission of UDP protocol in sonar signal processing

UDP is a mainly used transport protocol for high speed data transmission in Internet.The embedded UDP protocol was implemented based on FPGA.The using of UDP protocol improved the communication quality of the sonar system significantly.At the same time,implementation based on FPGA can reduce cost effectively,integrate other function modules easily to improve system integration,also the PCB board area and routing complexity are reduced,and the system′s reliability is improved.Therefore,the study has much practicality value for the embedded design.
