为了满足载荷与卫星进行可靠通信的目的，设计并实现了基于FPGA和BU?65170协议芯片的1553B远程终端。自行设计了用于控制BU?65170的主控制状态机，采用16位零等待缓冲接口模式，使用单消息和双缓冲模式进行消息传输。创新性地引入RS 422总线与1553B总线进行通信，方便测试过程，结果直观可见。采用专用测试板卡Alta ECD54?1553对系统进行测试，获得预期的可靠结果。FPGA取代传统CPU来控制1553B通信并集成数据传输功能，采用Verilog HDL硬件描述语言有利于软件移植，缩短研发周期，提高系统可靠性。

In order to realize reliable communication between payload and satellite platform, a 1553B remote terminal was designed based on FPGA and BU?65170. A FSM was designed to control BU?65170. The 16?bit zero latency buffering interface mode and single message/double buffering mode are adopted to transmite messages. RS?422 is used to communicate with 1553B for the convenient testing. In the test, an exclusive testing card Alta ECD54?1553 was employed, and a correct result was ob?tained. All of the control and data processing functions are centralized in FPGA instead of CPU. Verilog HDL is used for soft?ware transportation, R&D cycle reduction and reliability improvement.
