数字信号处理器DSP已经在诸多领域中得到了广泛的应用，同时DSP开发工具也得到了迅速的发展。本文在对各类DSP开发工具分析的基础上，将其归纳为低、中、高三个层次，分析阐述了每个层次的特点：低层工具提供了C语音编译器、实时操作系统、可供C语言调用的库函数、以及实时多重处理的特殊支持；中层工具提供了面向算法的开发、分析和学习工具可对数据进行时、频域等不同形式的处理；高层工具提供了数据流软件包帮助用户用方框图进行开发。最后对DSP开发工具的发展趋势进行了展望。
Digital signal processor DSP has been widely used in many fields, and DSP development tools have also been developed rapidly. Based on the analysis of various DSP development tools, this paper summarizes the three levels of low, medium and high levels, analyzes and expounds the characteristics of each level: low-level tools provide a C-language compiler, real-time operating system, C Language-specific library functions, and special support for real-time multiprocessing; mid-level tools provide algorithms-oriented development, analysis and learning tools that handle data in different forms, such as time and frequency; and high-level tools that help with data flow packages Users use the block diagram to develop. Finally, the development trend of DSP development tools is prospected.
