| 摘 要： | TMS320VC55x系列是TI公司推出的新一代低功耗DSP产品。因为该系列DSP没有片内Flash，所以需要外接Flash，从而需要解决程序的加载问题。本文详细介绍了在C55xDSP系统中实现Flash引导的方法。以基于TI公司TMs320vc5509A和SST公司的SST39LF200的数传平台为例介绍了一种利用Flash存储器实现DSP系统对主程序的上电加载的方法。

| Abstract: | TMS320VC55x series is a new generation product of DSP with low power consumption, which is manufactured by TI. Because the series of DSP is lack of Flash in the chip, so external Flash is needed, thus the problem of program boot-loading is required to solve. This paper introduces in detail the method of achieving the Flash booting in the C55x DSP system. By taking the data transmission platform based on Tl＇s TMS320VC5509A and SST＇s SST39LF200 as an example, a kind of method that the DSP can au- tomatically load the main program from the Flash to the RAM. |
