基于FPGA的可重构智能仪器设计

Reconfigurable intelligence instrument design based on FPGA

传统测试仪器普遍存在生产出来后普通用户难以改变其相对固定的功能,无法满足多样性的测量。基于此本文开发了基于FPGA的可重构智能仪器,利用SOPC Builder软件在FPGA中嵌入了NiosII处理器系统,采用可重构的应用框架技术利用HAL系统库进行软件设计。解决了由于测试对象复杂、测试设备多、测试资源利用率低所造成的测试系统的生产、维修成本过高,资源浪费等问题。

There is an all-pervading problem in the traditional test instruments that their fixed function can not be changed easily so it is unavailable when used the other objects and so it is generalization is restricted. A kind of intelligent reconfigurable instruments based on FPGA is developed. The Nios Ⅱ system is embed into the FPGA with SOPC Builder, and a technique reconfigurable frame and the HAL system library are adopted in the design of this system. The problems, such as high maintainable cost and resource wastes due to the complexity of the test object, the variety of test instruments and the low reusable are solved.
