摘　　要：按照模块化和标准化的要求,提出用CPLD和双口RAM来实现一种通用的寄存器基VXI接口电路的设计方案,使之满足基于VXI总线高频地波雷达所有模件的接口要求.具体描述了该接口的设计方法、主要的逻辑及时序关系,采用有限状态机并利用VHDL语言和原理图输入的混合设计成功实现了"双向中断、全双工"的块数据传输方式.它具有通信速率高、灵活性好、调试方便等特点.实际运行表明,该接口电路工作正常可靠.According to the requirements of modularization and standardization, the paper presents the design principle using CPLD and DPRAM of general purpose VXIbus register-based interface for High Frequency Ground Wave Radar (HF GWR) based VXIbus. It describes the realization method and main logic in detail. Taking advantage of VHDL and schematic designs, it successfully realizes the bidirectional interrupt and full duplex block data transfer function. The interface circuit has been verified in practice.
