中文摘要:

      音频管理组件（AMU,audio management unit）的BITE（built-in test equipment）使用ARINC429总线接口，其接口器件一般为16位数据总线。基于cPCI总线设计的板卡，使用DEI1016A作为ARINC429总线控制器和CPLD作为总线仲裁器，达到能够使用工业控制计算机实现AMU自动测试的目的，并且具有较好的可扩展性。

英文摘要:

      The BITE(built-in test equipment) of AMU(audio management unit) has an ARINC429 bus with interface of an 16 bit data bus.A design of cPCI peripheral board which uses DEI1016A as ARINC429 bus controller and CPLD as bus arbitrator regards is able to realize the purposed of AMU automatic testing by using industrial control computer,and has good expansibility.
