摘要
结合静电支承控制系统的任务要求，分析了主机与DSP系统间的多种通信方式。对采用16位ISA总线与双口RAM芯片IDT7025的接口电路设计进行了重点讨论，最后给出一个在WIN98下采用中断方式对IDT7025进行数据块读写的示例。
：The various data communication modes between a host PC and the DSP system are discussed in application of an electrostatic suspension control system． The paper focuses on the interface design between ISA bus and dual－port RAM chip IDT7025． A sample code based on WINDOWS98 is also presented to realize data communication by using mail interrupt function．
