设计人员经常需要给DSP增加一些过去由通用微控制器完成的实时通信和系统控制任务，因而使DSP固件（firmware）的应用变得越来越复杂。实时任务的增加会引发错误和时序方面的问题。DSP上的多重中断代码用传统的方法很难编程、优化和调试。尽管开发和调试DSP固件的工具近年有了 Designers often need to add some real-time communications and system control tasks that were previously performed on a general-purpose microcontroller to the DSP, thus making the application of the DSP firmware more and more complex. Increasing real-time tasks can cause errors and timing issues. Multiple interrupt code on DSP is hard to program, optimize, and debug using traditional methods. Although tools to develop and debug DSP firmware have been available in recent years
