Abstract: This paper introduces the necessity of studying technique of reconfigurable instrument and generalizes the process of designing it. The hardware aspect of design of the reconfigurable instrument: putting emphasis on introducing the present situation of FPGA which is the key of reconfigurable disposal. Meanwhile the software aspect: the developing method of domain applications is presented as “application framework & reusable components”, so the assembly problem of reusable components can be resolved successfully and the example of application is given.
