摘要
现代测试系统中,怎样保证各个模块之间的同步以及测量的实时性是一个非常重要的课题,反射内存网络因为内在的延迟确定、延迟时间短、支持跨平台等特点在实时系统中得到了广泛的应用;一种基于反射内存网络的实时测试系统设计方案被提出,该设计利用MPC8270将通用PMC反射内存卡的数据转换为VXI总线格式数据;该设计还可以使反射内存数据转换为任意格式数据,有很强的通用性;实际测试表明,该方案设计达到了实时性要求。
In modern test system, how to keep synchronization between different test modules and real time in measurements is an important problem. Reflective memory network is widely used in real-time systems for such characteristics, as confirmation in delay, short time delay, crossplatform ability. A new design of real-time test system based on reflective memory network is proposed, and the design adopts MPC8270 translating data from reflective memory to VXI bus. Furthermore, the design can be used in other systems for its ability translating data from reflective memory to any other formats. The experiment shows the design satisfy the real-time need.
