Embodiment Construction

[0019] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0020] Referring to Fig. 1, the present invention uses a 32-bit CPCI interface under a 3.3V signal environment to communicate with the host computer, and the communication cards communicate through optical fibers, and the optical fiber data transmission rate can reach 1.25Gbps. The present invention is mainly composed of several functional modules such as a control chip (using Virtex-II Pro FPGA) 1, an SFP optical transceiver module 2, a clock generation module 3, a power supply module 4, an ISP configuration PROM 5 and a CPCI interface 6. Figure 1 also shows the logical relationship and signal flow among the modules of the communication card.

[0021] The control chip 1 adopts the FPGA of Virtex-II Pro series products. The Virtex-II Pro series products are high-end FPGA products launched by Xilinx. Structure, and use IP (Intellectual Property, intel...

Abstract

The fiber serial communication card special based on Virtex-II Pro FPGA comprises: a control chip as the kernel, a light transmitting-receiving module connected with former chip respectively, a clock generation module to provide clock and reference time for Power PC; a power module, an ISP to configure control chip of PROM, and the CPCI interface to connected the control chip and CPCI bus.

Description

technical field [0001] The invention relates to an optical fiber communication device, in particular to an optical fiber (Fiber Channel, FC for short) high-speed serial communication card based on a Field Programmable Logic Gate Array (FPGA). Background technique [0002] Existing optical fiber communication basically uses application-specific integrated circuits (ASICs) + optoelectronic transceivers. Since ASICs are all aimed at a specific function, the flexibility of ASIC design is greatly limited. However, the internal logic function of FPGA can be changed with different applications, so it can be applied to various occasions and different standards. [0003] Han Xiaochun discloses an asynchronous two-wire full-duplex intelligent communication card in the invention patent application with the publication number CN1124894, which is characterized in that the memory, the asynchronous serial communication part 1 and the asynchronous serial communication part 2 are controlled ...
