[Abstract]:With the rapid development of information industry, communication, electronics, multimedia and other industries of data transmission speed and bandwidth requirements are increasing. How to achieve reliable, high-speed broadband data transmission has become a hot topic. Based on the above background, this paper designs a high-speed broadband data transmission and processing scheme based on PCI Express bus, which realizes the process of real-time data transmission and high-speed data processing from the computer to the target board. And through a series of experimental design, the performance of PCI Express bus is verified. This paper describes the PCI Express bus protocol, bus architecture and transmission mode. On this basis, a scheme for high-speed broadband data transmission and processing is described in detail from two aspects: logic design and software design. In the aspect of logic, the design scheme of PCI express and bus based on Altera Cyclone IV GX series development board is expounded, and the realization of PCI Express transport layer and data link layer by using Altera Hard IP is described in detail. The design process of physical layer. PCI Express application layer design is the focus of this paper. Based on the existing Altera Hard IP design, the FFT design is implemented in the PCI Express application layer and the existing links are partitioned. The performance of the PCI Express link is tested step by step, thus the transmission and processing of high-speed broadband data are realized. In the software part, the WinDriver with powerful function and short development period is used to design the PCI Express driver. The advantages and the design flow of using WinDriver to develop the device driver are mainly expounded, and the key API functions are described in detail. On the basis of this, the project of designing PC-side application program using MSVisual C 6. 0 development environment is given. In the last part of the thesis, the transmission performance of the whole design and the test results of each design are given. The design presented in this paper can run stably through function simulation and performance test at module and system level. The results show that the design can meet the requirements of high-speed broadband data transmission and processing.
