摘要
为了实现PC机与ARM控制单元之间的高速数据传输,设计了基于CH365的PCI通信接口卡。其中,选用双口RAM作为数据缓存,提高数据传输速率;使用CPLD芯片完成双口RAM和CH365局部总线接口之间的连接。经验证,采用本方法设计的PCI通信卡在实时性、可靠性、传输速度和电路图设计方面都有很大的优势,具有较好的应用前景。
In order to achieve high-speed data transmission between PC and ARM, a PCI communication interface card based on CH365 is designed. In this design, the dual-port RAM is used as a data buffer improving data transmission rate; CPLD chip is used to complete the connection between the dual-port RAM and CH365 local bus interface. After verification, the PCI communication card designed with this method has great advantage in real- time, reliability, transmission speed and circuit design, so it has a good application prospect.
