Reconfigurable Technology in the Application of Virtual Instrument

Abstract:

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 dynamic and static combination mode,the master 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.Modular standard hardware is the hard fundament for virtual instrument. The traditional hardware module is independent entity one by one, which make them inflexible in configuration and large in volume. Depending on the FPGA hardware and reconfigurable computing technology, the function of many instruments can be realized in FPGA. The dynamic configuration can realize new function and reduce the volume of the instruments, which make the function of virtual instrument more powerful and realize the virtual instrument in a real sense.
