基于ARM的便携式1553B总线测试系统的设计与实现

Design and implementation of portable 1553B bus test-system based on ARM

为了方便对1553B设备进行测试,介绍了一种基于ARM9平台和FPGA的1553B总线测试系统的设计与实现方法。该系统以LPC3250作为微处理器,以CYCLONE I系列的EP1C6Q240C8芯片实现ARM与1553B协议芯片的接口逻辑。在Linux操作系统2.6内核下实现1553B的驱动程序。1553B协议芯片采用BU-64843T8,以实现系统的便携性。

In order to make the process of testing 1553B devices convinent, we introduce a method based on ARM9 platform and FPGA to fulfill 1553B bus test-system.This system uses the LPC3250 as microprocessor, and CYCLONE I Family＇s EP1C6Q240C8 is used to implement the interface logic between ARM and 1553B chip .The 1553B driver is achieved in Linux 2.6 kernel. We use BU-64843T8 as 1553B protocal chip to make the system portable.
