Abstract

In order to overcome the problem that the high cost of system maintenance brought by DSP emulator debugging in field and the limitations of chip-level Bootloader, based on the study of the structure and Bootloader principle of DSP system, it adopts the module design method, the software and hardware system of remote update for DSP system program based Ethernet is developed. Hardware circuit based on DSP and DM9000 driven program is designed and it implements TCP/IP to embed DSP. The flexible use of external memories address re-mapping makes DSP programs can be loaded selectively and realize the self Bootloader.
