The Design And Implementation Of High Speed Low-error-rate Transmission System Based On FPGA

With the fast development of science technology, the data produced by huge electronic system such as radar, navigation, communication and electrical antagonism, increases in exponential way, which puts forward higher requirements for efficiency and stability of the transmission system. However, due to the limitatin of structure and transmission protocol, traditional data transmission system can not satisfy the practical requirement. It is of great significance to develop a kind of transmission system.With high efficiency and stability.This paper does a deep research on the design and realization of fast fiber communication system based on PCI Express protocol with use of FPGA, which has a great significance for developing efficient and stable transmission systems. The work of this paper are described as follow:Firstly, system reqiurement technology target is analyzed, the designing flow of the whole, mature system is brought forward and the system framework is built.Secondly, the hardware design of the system is completed, the design of each module is discussed, and PCB design is optimized.Thirdly, based on the platform of FPGA, the clock module, receiving module and transmission module based on Aurora are designed and simulated. For the purpose to satisfy the practical requirement .the data transmission based on hamming code and Aurora protccol is put forward, which highly improves error-checking and error-correcting ability of the transmission system.In the end, according to the software and hardware design of the system, testing environment is built and testing method is given. The influence of the key devices in the designing is simulated; the test method for speed and error rate of the whole system is brought forward; low error rate is verdicted form the eye pattern of the input signals . Testing results show that, the system satisfies the technology target and realize the designed requirment.
