| Abstract: | In recent years, DSP is widely used in speaker system and PA system. Because it can efficiently complete sound collection, filtering, crossover, equalization, anti-noise and feedback suppression algorithm, the audio workers have made breakthrough progress in sound processing. A key technology of DSP development is automatically bootloading. Based on TMS320C6727 floating-point DSP chip, this paper briefly analyze a high-speed serial loading technique. Finally in order to broking the size limit of program in the automatically bootloading process, this paper introduces a new type of secondary bootloader technique. |
