基于TMS320F2812的程序从FLASH到RAM的移植

TMS320F2812 DSP里，代码从内部Flash里运行，比从内部RAM里运行要慢30％左右，所以对运行时间苛刻的程序直接在Flash里运行，往往不能满足要求。需要将代码移植到RAM以提高运行速度。主要研究TMS320F2812数字信号控制器的初始化编译段从片内Flash复制到片内RAM，在运行的时侯达到优化执行速度。方案实现了在开机后，程序执行到C_int00 c函数之前来直接实现这一功能。

Transplant Procedure FrOm FLASH to RAM Based on TMS320F2812

TMS320F2812 DSP,when in the operation,the code from the internal Flash running about 30 percent slower than from internal RAM.So,direct operate in Flash for the harsh appliation,often can not meet the requirements.Therefore,there exist a need to copy the code to RAM to enhance the operating speed.This application report and associated code files provide functionality for copying initialized compiler sections from the internal Flash memory to the internal random access memory （RAM） of the TMS320F2812 digital signal controllers at run time for optimizing execution speed.The solution provided implements this functionality directly after booting before entering the c int00 C entry routine.
