A virtual instrument results from the combination of a general purpose computer with a generic data acquisition system in order to emulate a traditional measurement instrument. The data acquisition hardware of the virtual instruments provides computers with input/output capability and is usually based on the integration of standard circuits with fixed architecture. Meanwhile the software defines the analysis and processing of the acquired data that is the function of the generated virtual instrument. As a consequence, the virtual instruments are characterized by their versatility and low cost but they lack of performance of the application oriented hardware architectures. In this paper, we present a virtual instrument system based on reconfigurable hardware that improves the features of virtual instruments preserving their versatility and low cost. 1. Introduction The emergence of virtual instrumentation is a revolution in the history of the development of measuring instruments. It fully utilizes the latest computer technology to implement and extend the instrument function. Using the image of a computer screen can be easily simulate a variety of equipment control panels to the needs expressed in the form of the output of test results. Using computer software to achieve most of the signal of the analysis and processing to complete a variety of control and test function. The user through the application of general-purpose computer program modules and features of the hardware together. Through friendly graphical interface to operate this computer. As in operating their own definition of individual instruments of their own design can be measured to complete the acquisition, analysis, determine, control, display, data storage and so on. Virtual Instruments advantages of more traditi
