A research on high-speed and large-capacity interface technology basing on fiber channel

摘要

To meet the demand of complicated ATP system to control in real time and smoothly, this paper selects fiber channel as the data transmission mode. It designs a star-shaped electrical platform which can combine data acquisition, processing, transmission, and exchange in one. Also by using Rocket I/O GTX transceiver embedded in Xilinx Virtex-6 FPGA as the physical layer, it implements real-time data transmission and exchange basing on 24 fiber channels to support up to 128 custom serial protocols. The main points of electrical platform design are presented in this paper. Furthermore, the method of FPGA implementation and major configuration parameters of Rocket I/O GTX transceiver are discussed in detail. Also the experimental results of hardware debugging in ISE environment show that the 24 fiber channel transmission is stable and right when the system reference clock is 250MHz, single-channel line rate is 2.5Gb/s. The use of fiber channel has improved data transmission efficiency and reliability between the units of ATP system. Also hardware debugging workload is significantly reduced by universal configurable software design.
