With the continuous development of technology in the field of avionics and the increasing requirements for the internal bus speed,the SRIO bus plays an increasingly important role in it.The various processors such as PowerPC and DSP are capable of implementing SRIO node’s function,but these processors cannot meet the increasing localization needs.The FMQL series programmable fusion chips independently developed by Shanghai Fudan Micro have been widely used,but they do not have a complete SRIO bus implementation solution.Based on the FMQL platform,the SRIO bus technology is studied that supports multi-protocol mixed transceivers,and enables a single chip to provide 16 SRIO nodes,and each node can communicate with 32 other nodes,and builds a hardware test environment to verify the reliability and stability of this technology.
