The development of micro satellite space plug-and-play architecture technology depends on the ability of these protocols on the bus response in the communication network. SpaceWire is a protocol designed for spaceborne communication network as the main network in topological structure. Space plug-and-play architecture is proposed by AIAA for quick response satellite. However, most of the payload in use are non SpaceWire interface, for instance, 1394b for fiber gyro and RS422 for infrared camera. In this case, this article studied the data transition principle of 1394b and serial port protocol integrate into space plug-and-play architecture by SOC and validated its soft/hardware on FPGA.
