针对SpaceWire的应用需求,在对SpaceWire标准协议及其路由机制介绍的基础上,设计并实现了1种SpaceWire路由器。路由器以FPGA为核心,带有8个SpaceWire链路接口、2个USB总线接口以及1个Time_Code接口,采用Verilog HDL硬件描述语言设计开发SpaceWire路由器IP核。经过对SpaceWire路由器数据传输的可靠性和实时性测试,结果表明SpaceWire路由器通信速率可达200 Mb/s,数据传输具有较高的可靠性和实时性。
Aiming at the application requirements of SpaceWire, a SpaceWire router is designed and implemented based on the introduction of SpaceWire standard protocol and its routing mechanism. The router takes FPGA as the core, with 8 SpaceWire link interfaces, 2 USB bus interfaces and 1 Time_Code interface, and designs and develops the SpaceWire router IP core using Verilog HDL hardware description language. After the reliability and real-time test of SpaceWire router data transmission, the result shows that the communication speed of SpaceWire router can reach 200 Mb / s, and the data transmission has high reliability and real-time performance.
