4.3 Limitations

The limiting factor for this implementation is the amount of internal RAM available on the TMS320F28xxx DSCs. This limits what projects can implement this functionality. If the project is too large to fit in the RAM, this functionality cannot be implemented.

Since the C2000 platform is geared towards motor control and digital power applications, Texas Instruments provides numerous software packages for these types of applications (References 11,12,13). For more information, see F280x Motor-Specific Software Solutions - APSF280x (http://focus.ti.com/docs/toolsw/folders/print/apsf280x.html), TMS320F281x Motor-Specific Software Solutions (http://focus.ti.com/dsp/docs/dspplatformscontento.tsp?sectionId=2&familyId=1406&tabId=2027), and the TMS320C2000™ Controller Digital Power Software Library (http://focus.ti.com/dsp/docs/dspcontent.tsp?contentId=25262).

As supplied, these software packages run from the internal RAM. This demonstrates that these control systems can be run from the internal RAM as the base project is small enough to be allocated to this memory.
