摘要:

针对某型导弹多总线地面测试设备传输数据量大、传输速度高的要求，设计了一种基于乒乓操作的SDRAM控制器作为测试设备数据缓存器。详细介绍了以FPGA为主控器的设计方案，包括SDRAM内部接口设计、数据传输过程以及乒乓操作的实现方法。通过图像发生装置将图像数据发送给测试总线，对控制器功能进行验证，数据读写速率稳定达到125 Mbit/s，证明本控制器具有良好的性能，能够满足多总线地面测试设备的需求。

Abstract:

A double SDRAM controller based on ping pong operation as the data buffer is designed to meet the requirement of large data amount and high transmission speed for multibus ground-based test equipment of a missil e system. The design scheme which uses FPGA as the main controller is presented i n detail，including the internal interface of SDRAM, process of data transmissio n and realization of ping-pong operation. The function of this controller is val idated through the picked images from image generator,and the result shows that it can write and read dat a at the steady rate of 125Mbit/s,which indicates this SDRAM controller is feasible for the multibus ground-based test equipment.

Key words: ground-based test equipment multibus SDRAM controller ping-pong operation
