主机与智能接口卡间信息交换方法的研究

Study of Information Exchange Methods between a Host and an Intelligent Interface Card

对PC主机与基于PC总线且采用 80 31CPU构成的智能接口卡之间并行交换信息的原理进行了研究 ,进而给出了采用锁存器、双端口SRAM和FIFO存储器实现PC主机与智能接口卡间并行交换信息的三种具体实现方法 ,并对这三种方法的原理及特点作了深入分析 .对于设计智能接口卡具指导意义和实用价值 .

The theories for exchanging information parallely between a PC host and an intelligent interface card that is based on PC bus and uses a 8031 CPU are researched,and then,three concrete methods using latches,dual port memories and FIFO memories are granted for parallel information exchange between a PC host and an intelligent interface card,and the theories and characteristics of these three methods are analysed profoundly.It has guiding significance and practicability for designing intelligent interface cards.
