在雷达回波记录与重演设备中,采用132MB、33MHz的PCI局部总线可以实现高速数据传输。而PCI总线接口控制器的设计是雷达回波记录与重演中的关键。本文对雷达回波记录与重演设备中的PCI总线目标接口控制器的逻辑功能及其状态机进行了比较细致的描述,利用max+plusII实现了PCI目标接口控制器的功能仿真,并得到了仿真时序图。该仿真对于实际接口的设计与实现具有一定参考价值。
In radar echo recording and replay equipment, using 132MB, 33MHz PCI local bus can achieve high-speed data transmission. The PCI bus interface controller design is the key to radar echo recording and replay. In this paper, the logic function of the PCI bus target interface controller and its state machine in the radar echo recording and replay equipment are described in detail. The function simulation of the PCI target interface controller is realized by using max + plusII, and the simulation Timing diagram. The simulation has certain reference value for the design and implementation of the actual interface.
