Abstract

When TMS320F28XXX DSP programs run from the on-chip flash, it’s about 30% slower than that from the on-chip RAM, which caused the poor performance when programs run directly from on-chip flash, so program code need to be transplanted to RAM in order to improve the running speed. This paper analyzes the running processes of TMS320F28335 DSP application and the code removal processes from on-chip FLASH to RAM, and then introduces the transplantation programming method. This method is verified feasible through the experiment designed in the project of gun control system based on DSP TMS320F28335, and it can be extended to practical engineering and industrial applications.
