Title    The design of display and control terminal based on AT91SAM9G20                                                

Abstract With the development of information technology, intelligent and networked, embedded system technology get broad space for development. ARM processor is a 32 bit embedded industry-leading microprocessor .It is became the first choice of many embedded solutions, with low power consumption, high performance and scalability. So the design of ARM processor embedded system is became a more and more important subject.

The paper is to design an embedded system based on AT91SAM9G20 processor independently, with the application background of a radar signal simulator display and control terminal design. The system realizes the function of signal processing and production, working status monitoring, data storage and transmission, through the control of the FPGA, LCD, keyboard, external interface. Firstly, architecture of system is designed, according to the application requirements. Secondly, it’s followed by introduction of system hardware and software design. Finally, it’s to verify and demonstrate the function of the system, and verify the correctness of the design.
