Abstract: Virtual instrument systems based on industrial computer or PC take the role as main platform of smart testing systems for long time. As the era of post-pc comes on, requirement for more customized and more tiny instrument becomes more and more eager. Maturation and wide use of embedded systems make it a new way to construct a embedded instrument that based on single board computer (SBC) and data acquiring board.
In this paper, critical techniques have been proposed to construct embedded instruments that based on pc-104 bus based single board computers (SBC) and function boards.
