摘要
主要研究以可重构计算技术为基础的虚拟仪器实验系统,系统分为计算机、主控FPGA、可重构FPGA以及仪器端口驱动等部分,采用动态和静态相结合的方式,通过主FPGA选择不同的下载程序以实现对从FPGA的重构;设计计数器及函数发生器两个功能模块对虚拟系统的重构性能进行了验证。可随时更改实验功能,加速产品研发速度并降低产品成本。
In this paper,the main study is virtual instrument experimental systems based on reconfigurable computing technology.The system is divided into a computer,the master FPGA,reconfigurable FPGA,and instrumentation port drivers,adopting dy-namic and static combination mode,the main FPGA chooses a different download programs to achieve the reconfiguration of slave FPGA;through designing two functional modules of counter and function generator,reconfigurable performance of the virtual system is verified.
