Because of the virtualization of the Java virtual machine (JVM) instruction set, the current Java chips interface between software and hardware has to expand the instruction set.

For analysing of the way of practical application of ATT7022B in ARM in detail,the identity and principle of energy chip ATT7022B are introduced,and combining with the applications of protection devices in the mine for the parameters collection,the design of LPC2292 and ATT7022B hardware interface and software programming are given.

According to the demand of the development of a configuration software for electric system monitoring and control,the hardware interface based on OPC specification for data communication between PC applications and SIMENTIC S7300 PLC is presented, including its general architecture and the implementation of different functions.

The author proposes an opening hardware interface model and illustrates the way of implementation.

Development and application of interface software for the network plotter.;

The structural method of interface software is given.

From this point of view,we describe the concept of standard,general graphic descriptive language and descusse the design principle and technic realization of a open-ended plotter interface software.
