为了提高某国产化有线单元测试台的传输速度,提出采用FMQL系列芯片作为主控芯片进行指令数据的下发与上传。基于FPGA的以太网数据传输应用广泛,但国产芯片中支持千兆以太网的控制器芯片极其匮乏,导致实现全国产化千兆以太网的传输非常困难。针对这一问题,提出利用集成ARM与FPGA的FMQL系列芯片作为主控芯片,在该芯片内部通过AXI-Stream总线与背板总线的协议转换,完成了测试台背板总线与上位机的数据传输,速度达到20 Mbps,能够满足功能需求。

In order to improve the transmission speed of a domestic wired unit test-bed,FMQL series chips are proposed as the main control chip to transmit and upload command data.Ethernet data transmission based on FPGA is widely used,but there are very few controller chips supporting Gigabit Ethernet in domestic chips,which makes it very difficult to realize the transmission of Gigabit Ethernet produced in China.To solve this problem,FMQL series chips integrating ARM and FPGA are proposed as the main control chip.Through the protocol conversion between AXI-Stream bus and backplane bus,the data transmission between backplane bus and host computer is completed,and the speed reaches 20 Mbps,meeting the functional requirements.
