针对数字信号处理器(DSP)没有内置用户可编程非易失性存储器的特点,该文以TMS320VC5410型DSP为例设计了一种通用的在DSP外部扩展Flash存储器并实现脱机运行的解决方案.这种方案使DSP在在线调试成功后可以立即实现程序自举加载和脱机运行,从而大大简化了DSP的开发难度,使繁琐的自举加载工作可以仅点击几下鼠标即可完成.开发人员能够像使用Flash型单片机一样简捷高效地进行DSP开发.%Digital signal processors(DSP) usually have no embedded user-programmable nonvolatile memory characteristics.For making up this shortcoming, we designed an offline operation solution using DSP and external Flash memory.In this paper we introduce it as TMS320VC5410.Using the solution, we can make DSP automatically bootload and run immediately after online debugging successful.So this solution reduces the difficulty of development and accelerate the development cycle, it also make developers using DSP as efficient as using MCU with embedded Flash memory.
