【摘要】 为了实现FPGA与PC之间高速数据的双向同时传输,设计了采用PCI接口实现的双向高速传输系统。系统中采用PCI9054作为PCI接口芯片连接PCI总线与FPGA,并通过PCI驱动程序的设计来提高数据传输效率。经过测试,该系统的速度在双向传输上可以同时达到至少80 Mb/s的速率。该系统可以应用在PC与FPGA之间需要大量数据交换的场合。更多还原

【Abstract】 For the need of bidirectional high speed data transmission between FPGA and PC,the paper designs a bidirectional transmission system based on PCI interface.The system connects PC and FPGA by the PCI bus interface chip PCI9054,and with the design of PCI driver to improve the efficiency of the transmission.After testing,the data transmission speed of the system can reach at least 80 Mb/s on both transmission directions.The system can be used on the occasion which need high speed data exchange between PC and FPGA.更多还原
