摘要
近年来,DSP被广泛用于扬声系统和扩声系统系统,其能高效的完成音频信号的采集、滤波、分频、均衡、抗噪和抑制反馈等,这使得音频工作者在声音处理上取得了突破性的进步。而自动加载外部存储器中的应用程序是DSP开发过程中的一项关键技术。基于新型的音频处理芯片TMS320C6727介绍一种高速的串行加载技术,且打破传统自动加载对程序大小的限制,介绍了二次加载技术。
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, a high - speed serial loading technique is analyzed briefly in this paper. Finally in order to break the size limit of program in the automatically bootloading process, a new type of secondary bootloader technique is introduced.
