Abstract :
In order to overcome the problem that the high cost of system maintenance is brought by DSP and MSP430 emulator debugging in field. Based on research of the system structure and the procedure bootstrap principle, adopt the module design method, the software system of remote update for DSP and MSP430 system program based Ethernet is developed on the hardware platform of VOIP telephone communication system, and realized the TCP/IP protocol to embed DSP. The flexible use of external memories address remapping makes system programs could be loaded selectively and realizes the self-loading of the DSP and MSP430MCU programs.
