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.
