[Abstract]:With the advent of big data era, the transmission and storage of mass data put forward the requirements of higher transmission rate, larger bandwidth, more convenient and more secure transmission mode. Bus technology based on high-speed interconnection has developed into multi-type and multi-rate mode. Fiber channel technology has become a hotspot in the field of high-speed interconnection with the characteristics of super high speed transmission rate (up to 10Gbps transmission rate), good anti-interference performance and stable transmission quality. Through the research on the development of optical fiber channel technology and the analysis of the demand for high-speed data transmission, the third kind of service of optical fiber channel technology is chosen as the design object of this paper. Based on the detailed analysis of fiber channel protocol architecture and the flexible architecture of programmable logic device (FPGA), it is suitable for high-speed bus development. The logic design of Fibre-channel protocol in ALTERA Stratix IV chip is presented. The logic design of Fibre-channel protocol is accomplished by Verilog hardware description language. The function design and implementation process of FC-0 layer FC-1 layer and FC-2 layer are described in detail in this paper. The data transmission index of the highest 8.5Gbps is completed, and the third kind of service of point-to-point topology is supported. The main design contents of this paper include: (1) realizing the function of FC-0 layer by designing SFP optical module and high speed serial transceiver in Stratix IV, converting high speed serial fiber link data into 40bit low speed parallel path data 2) designing 8B/10B codec. The transmission word boundary alignment, synchronous state machine and port state machine realize the alignment operation of primitive data, and the aligned data is sent into the synchronous state machine to complete synchronous detection, and the synchronous primitive data is sent into port state machine to push forward the link state. When the link is activated, the data is assembled and transmitted according to the standard frame format through the design of frame sending state machine. To realize the transmission and reception of frames in FC-2 layer, the communication parameters of both ports can be negotiated by designing the interaction of link extension service data frames, and the architecture login and port login are realized in the FC-2 layer. The design of process login and port logoff is based on the design of buffer to buffer flow control strategy, which can control frame receiving and frame sending, and complete the control of the whole communication state. At the end of the paper, the corresponding simulation and test of each module of fiber channel system are carried out. The test includes board level time domain signal test and logic test of each module. By analyzing the initialization of high-speed transceiver, port state machine interaction, frame synthesis and frame transmission, architecture login, port login, process login and so on, the paper verifies the activation of optical fiber link. Login and registration status, flow control strategy and other design reached the target requirements.
