摘　　要：为了实现对某型装备BIT设计的验证工作,提出了一种基于嵌入式DSP处理器的故障注入系统体系结构,USB接口作为嵌入式系统与外界主控计算机的通信接口,是实现故障注入任务的关键,文章主要针对USB接口的实现问题进行研究,围绕系统的硬件设计、固件程序设计以及驱动程序进行设计。实际应用表明,该系统可以完成BIT设计的验证任务,对提高装备测试与诊断能力具有重要意义。To realize the validation of certain equipment＇s BIT design, the architecture of fault injection system based on embedded DSP is put forward. USB interface is taken as the communication interface between embedded system and external host computer, so it is the key to realize fault injection. The realization of USB interface is researched and the design of system hardware, firmware program and drivers are discussed in this paper. Applications show that this system can complete the validation of BIT design. And it is significant to improve the capabilities of equipment test and diagnose.
