Through hardware thread interface design and operating system kernel extension,this model makes it easy for designers to implement software/hardware partition from the unified thread view.

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.

Based on analysis on hardware connection and program design, the article probes into the experimental device in which microprocessors laboratorial instruments and LED lattice screen are well combined, and optimizes the equipment that enhances students microprocessors application skill.

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.
