Research On SDH Signal Processing Based On PCI-Express Bus

Since ITU-T formulated SDH standard in 1988, SDH has been widely applied in the telecom network. SDH is an optical-based carrier network combining with the intelligent network technology. With the application of SDH, it will largely improve the utilization ratio of the network resources and greatly reduce the expenses of maintenance and management.One of the important technology in SDH disposing is signal confirm and connection coding demultiple.Because of its high velocity, common arithmetic is not enough. Area dismember index arithmetic take the data into dismember disposing. Judge the date if it is hitted directly.PCI Express, which has been suggested by Intel in 2001 as the third generation I/O interconnection standard, is used to replace the traditionary PCI/PCI-X bus. Key PCI attributes, such as its usage model, load-store architecture, and software interfaces, are maintained, whereas its parallel bus implementation is replaced by a high-speed, fully serial interface. Further more, PCI-E takes advantage of recent advances in point-to-point interconnects, Switch-based technology, and packetized protocol to deliver new levels of performance and features.This thesis tells the SDH connect disposaling,and PCI-E bus design,and table a arithmetic base on FPGA.And implement the design. The dissertation is not only practical but also meaningful.
