Abstract: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.
Keywords:reflective memory network  real time  test system  synchronization
