摘要
提供了一种4路串口转换PCI总线的设计方案。运用Altera公司的FPGA芯片EP2C35和UART串口扩展芯片ST16C654实现多路串口和PCI总线接口转换,并重点介绍了FPGA和PCI总线的设计要点以及驱动程序的开发。该扩展卡符合PCI 2.2规范,最高波特率可达921.6 KB/s,可广泛应用于各类测试设备、工厂自动化、有线通信等领域。
A design on PCI bus of four-serial port switch is proposed in the paper. The multi-serial port interfaced to PCI bus is realized by using the FPGA chip EP2C35 of Altera company and UART serial expansion chip ST16C654. The main points of FPGAand PCI bus design and development of driver software are emphatically described. The extending card is up to PCI Rev. 2.2 and the maximum baud rate can reach 921.6 KB/s. So it could be widely applied in such fields as test equipments, plant automation, wire communication, etc.
