Abstract: Aiming at improving the reliability and validity of the remote update, making up the shortage of the traditional update system, a type of remote update system for single chip micyoco(SCM) with in-application programming(IAP) function was designed. The overall implementation framework of the system was introduced. The program structure within SCM, the subdivision of user code area in Flash code space and the design for system security were mainly described. And taking MSP430 SCM as an example, combining with C and assembly language, the concrete realization of the update system based on IAP technology and GPRS communication technology was further introduced. The test results of the prototype show that the system achieves the requirements of the design performance and realizes the desired functions, and it can be widely applied to various designs, such for intelligent instruments.
