摘要
Microblaze是Xilinx公司设计一种软核SOPC,它是FPGA芯片内部逻辑组成的一种32位软核嵌入式处理器。为了实现数据从FPGA到计算机的高速传递,本文介绍了一种基于u IP及Lw IP的网络协议栈,提出了一种可靠UDP(reliable UDP,RLUDP)协议,并完成了嵌入式TCP/IP协议栈设计与实现,实现了PC与MicroBlaze的高速数据传输,并对其性能进行了简单的测试,最终达到了设计要求。
Microblaze is a kind of soft-core SOPC designed by Xilinx. It is a 32-bit soft-core embedded processor that consist of FPGA logic units. In order to achieve high-rate data transmission from FPGA to computer, a reliable UDP（RLUDP） protocol is proposed in this paper based on u IP and Lw IP network protocol stacks. This paper introduces the design and implement of embedded TCP/IP protocol stacks, and illustrates the high-rate data transmission between PC and MicroBlaze according to the proposed protocol. Simple test on system performance is described, which shows that the designed system meets the design requirement.
