中文摘要:
      利用89C52单片机和双口RAM IDT7132设计了智能ARINC429总线接口卡。采用单片机使接口卡具有了自动数据处理能力,实现了智能化;采取双口RAM作为单片机和ISA总线数据交互媒介,提高了传输速率。讨论了双口RAM的地址空间分配和数据共享冲突仲裁问题,对接口卡的软件设计做了介绍。应用表明,所设计的接口卡具有传输速率高、可靠性好等优点。
英文摘要:
In the design of the intelligent 429 bus interface card,a single chip processor and a dual-port RAM are used.The card can deal with the communication data automatically and quickly.Using the dual-port RAM as a single chip and ISA bus data mutual media,the transmission velocity is improved. The address space allocation of dual-port RAM and a share conflict arbitration are discussed.The software of interface card is introduced. Its results show that it has advantage of high velocity and good reliability.
