摘　　要：介绍一种基于USB总线技术的信号调理平台的硬件设计方案。设计中采用Cypress公司的EZ-USB作为接口控制芯片,利用EZ-USB的软配置特性,通过加载不同的固件完成对不同被测对象的测试任务;信号调理平台的核心控制采用Lattice公司推出的ISP芯片,实现复杂的信息控制与数据交换。This paper mainly introduces a hardware design of signal conditioning platform based on USB bus technology, In this design, interface chip adopts EZ-USB chip produced by Cypress Company. Using soft-confignration characteristic of EZ-USB, test task for different test objects can be completed by loading different firmware programs. The key control parts of the signal conditioning platform adopts ISP chip orodueed by Lattice Comoanv. to realize complex information control and data exchange.
