In the field of complex embedded computing,the speed and scale requirements of multi-channel data transmission are getting higher and higher.The overall principle design of a multi-channel high-speed interconnect information processing system is presented.The core components of the system are three FPGAs,one PPC and one SRIO.In order to realize multi-channel 10Gb high-speed signal communication inside and between boards,the system uses a large number of high-speed transceivers of high-performance FPGAs to carry out reasonable functional design,GTH clock design and host-side loading design.The FPGA GTH test inside and between the boards shows that the system can achieve the receiving of 96-channel 10G high-speed data signals from other boards,send 56-channel 10G high-speed data signals and 12-channel 10G high-speed optical signal data,and interconnect 32-channel 10G high-speed data signals in the board.This system has the characteristics of high integration,high bandwidth and high speed.After experimental tests,its performance is stable and it has good practical results.
