Copying Compiler Sections From Flash to RAM on the TMS320F28xxx DSCs

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 TMS320F28xxx digital signal controllers (DSCs) at run time for optimizing execution speed. The solution provided implements this functionality directly after booting before entering the c_int00 C entry routine.
