摘　　要：为了实现过程监控的PC机与控制计算机之间的高速并行数据传输,设计了基于PCI9054的数据通信接口卡。使用PCI9054芯片作为PCI接口桥接芯片,将复杂的PCI时序逻辑转换为简单的用户时序逻辑,同时采用Altera公司的MAXⅡ系列CPLD芯片完成辅助控制逻辑,共同实现PCI局部总线接口到外部并行接口之间的接口转换,提出了通过CPLD编程设置接口卡的特殊功能寄存器和双向数据缓存的设计思路。To realize the data transmission between process monitoring computer and control computer,a data communication interface card based on PCI9054 was designed.PCI9054 was used as PCI interface bridging chip;the complex PCI temporal logic was transferred into simple user temporal logic;and MAXⅡ family of CPLD chip from Altera company was applied to complete auxiliary control logic;the interface transmission between PCI interface and external parallel interface was then achieved.The design idea was put forward through CPLD programming to set special function register of interface card and two-way data cache.
