摘　　要：提出了一种可重用的VXI系统的实现方法;该系统的硬件结构是使用PPC405GP和FPGA来实现,并采用了一种简单且通用的总线和功能模块进行通信;这种系统结构使得该系统的功能升级和扩展变得非常容易,接口电路的设计也很简单;基于该平台,开发人员只需将接口定义了解清楚,就可以进行VXI产品的开发设计,而不需要花费大量的时间和精力来学习CPU系统以及VXI总线;该设计方法已成功应用于产品开发,应用结果表明,该设计方法的引入极大地提高了VXI产品的开发效率。A method of realizing a reusable VXI system is presented. The system＇ s hardware architecture is based on PPC405G Pand FPGA, and the system uses a simple, common bus to communicate with functional modules. This architecture makes the system upgrading and function expansion has become very easy, and the design of interface circuit become simply. Based on this platform, developers can design VXI product only need to clearly understand the interface definition, and without the need to spend a lot of time and effort to learn the CPU system and VXI bus. This design method has been successfully applied to product development. Application results show that the introduction of the design method greatly improves the development efficiency of VXI product.
