| Abstract: | Because of the limitation of missile borne computer dimension and structure, it is hard to renew DSP program. Put forwards the DSP programming method based on serial port. Takes the example of the DSP processor TMS320C6747, which is the common processor for missile borne computer, analyze BOOT of DSP, give the implementation method of serial port programming realization process and key steps, and carry out testing. The result shows that the method is stable and reliable, and can solve renew and programming problems of DSP program. |
