摘　　要：在现代数字信号处理系统中,通常需要实时传输大量来自传感器的数据。为了验证系统的可靠性、稳定性和实际处理性能,需要一种能够模拟传感器组件将构造的仿真测试数据和真实实验数据导入数据处理系统的测试设备,特别是当硬件部分改动升级后,软件模拟无法完成测试目的时。而通用串行总线具有高数据传输率、无需配置、即插即用等特性,完全满足这种传输任务的要求。设计了一种基于EZ-USBFX2的高速数据传输系统,再配合有限状态机逻辑控制,将数据分配成满足数据处理系统要求的格式。该测试系统已成功运用到声呐系统测试中,并成功的发现了原系统存在的问题。实践表明,该测试系统稳定可靠,通过改变控制逻辑对数据的分配方式可兼容不同数据处理系统,具有良好的多用途性。In modern digital processing system, packs of data from sensor needs real time transmission. We need a test system for reliability, steadiness and real processing performance validation. This system should make test data act as data from sensor, and pour them into processing system, especially when software simulation does not work after hardware upgraded. The USB which has high-speed streaming data and can plug and play meets the requirement of the data transfer mission. A high-speed streaming data transfer system based on EZ-USB FX2LP and controlled by FSM logic to distribute data in required form is designed in this paper. This design has been used for Sonar system testing, and found bugs. It works stably and with highly flexible, it can work with many hardware data interface by a few adjust on data distribution form.
