Intelligent Design Of Radio Transmitter's Micro-controller Based On S3C44BOX Embedded System

With the coming of information era, radio broadcast becoming more and more automatically. Radio system bring forward new requirements to transmitter, which is not only upgrade the automation of it but also remote control with telephone network or internet. Because micro-controller is an important part of radio transmitter, so the research is much meaningful for upgrading automatic level of our radio transmitter technology. This paper describes how to design a micro-controller with ARM Embedded Microprocessor using computer, network, electronic technologies.Beginning of radio transmitter's applicant environments and Embedded Microprocessor's design ideas, the paper describes the function, construction, and characteristics of the micro-controller. As the control unit of radio transmitter, micro-controller take charge of monitor machine state, dispose malfunction, and turn on or shut off the machine on schedule. Because of electromagnetism disturb, we must think of how to improve anti-jamming capability of micro-controller. So during implement of our design, we adopt modularization method, Include main , I/O , man-machine interface , communication module.The main module is SAMSUNG'S 32bits microprocessor S3C44BOX;I/O module is MAXII CPLD chip EPM240;man-machine interface module using popular LCD technology, which combine with keyboard can operation capitally;communication module include USB, Ethernet, UART.Finally, we implement special technologies in hardware and software anti-jamming.
