摘要 为了适应数据传输高速度、大容量、实时性的要求,设计了基于FPGA的高速数据传输系统。该系统在硬件设计上以Altera公司的Cyclone Ⅳ系列的FPGA芯片和Marvell公司的千兆以太网芯片88E1111为核心;用FPGA的内部逻辑资源实现系统的收发控制功能,该方法可以增强FPGA代码的可移植性;为了实现接口数据传输的高效、简单易实现,FPGA与千兆以太网芯片的接口采用改进后的GMII作为接口。在FPGA上实现的高速数据传输系统,有效提高了数据的传输速度、吞吐量以及系统的可移植性。 To accommodate data transmission with high-speed,high-capacity and real-time requirements,this paper designs a system based on field-programmable gate array (FPGA) with high-speed data transmission.The system with hardware design bases on chips of Altera's Cyclone IV FPGA family and Marvell's chip of 88E1111 Gigabit Ethernet;The Send and receive control of the system is based on internal FPGA logic resources,the method can enhance the portability of FP- GA code.in order to achieve efficient interface for data transmission,which is simple and easy to implement,the interface of FPGA with Gigabit Ethernet's chip is designed as GMII.The system with high-speed data transmission bases on FPGA,the data transmission speed and throughput is effectively improved,and the portability of the system is also improved.
