[Retracted] Application of Virtual Instrument Technology in the Teaching of Embedded System Course

Table 2

Comparison of virtual instrument and traditional instrument.

Instrument classification	Traditional instrument	Virtual instrument
Features	Functions that are defined by the instrument manufacturer	Functions that are defined by users
Connection situation	Very limited connection with other equipment	Ability to connect easily with network peripherals and various instruments
Interface situation	Small graphical interface, manual reading of data, and small amount of information	Graphical interface, computer directly read data and analyze and process
Data that can be edited	Data that cannot be edited	Data that can be edited, stored, and printed
Important portion	Hardware	Software
Price cost	Expensive	Low price, only one-fifth to one-tenth of traditional instruments
Performance situation	Closed system, fixed function, and poor scalability	Open functional modules based on computer technology that can form a variety of instruments
Technology update speed	Slow	Fast
After-sales maintenance cost	High development and maintenance costs	The structure based on the software system that can greatly save development costs
