| Abstract: | Based on the structure and bootloader principle of DSP system, a method for the remote updation, debugging and self-loading of DSP system is developed by Ethernet. Hardware circuit and DM9000 driven program are presented and TCP/IP protocol is embedded into DSP. Through the re-mapping of external memory address, it is easy to implement the load of program section selectively and DSP self-boot. The experimental results show that the problem of high cost in system maintenance by conventional field debugging b... |
