The newly developed 32 bit ARM microcontrollers can work at a high frequency as several hundred MHz,thus solve the real time problem,which constantly troubles the engineers.

Base on nowadays functional requirement and limitation of measuring scheme for electromagnetic relay, from analyzing its operational principle, a new way is introduced to design and realize the smart test system, in which an ARM microcontroller working with stepper adaptive algorithm together was used as kernel part of system.

From the perspective of application, the embedded real-time operation system, μC/OS-II, is transplanted into the fluxgate compass whose core is ARM MCU.

A low-cost MINS/GPS integrated navigation system based on the MIMU and ARM MCU was designed in this thesis.

As a cost-effective, high-performance micro-controller solution for embedded systems, ARM micro-controller used more widely.

Ultrasonic wind velocity measurement with time-difference method and wind velocity measurement system based on ARM micro-controller were introduced.

This paper considers IPX communication between 32 bits microcontroller ARM and DSPEC as the example,it is introduced detailedly,that the interface between RTL8019AS and ARM,and the design of RTL8019AS ethernet drive program,and data frame format and its meanings of IPX protocol,and packing program and unpacking program design of IPX communication based on ARM.
