Similarly, the base voltage can be selected as the peak of maximum measurable phase voltage in the
system. Assuming that the dc bus voltage is 400V, base voltage is selected as 400V/√3.
2.6 DMC Systems: Legacy VS controlSUITE
There are basically two separate TI DMC systems offering similar solutions for motor control with minor
differences. These differences can be summarized as:
• controlSUITE supports Piccolo (2803x, fixed point) and Delfino (2833x, floating point) whereas Legacy
supports 280x and 281x (both fixed point).
• In controlSUITE the DMC Library modules are optimized macros whereas legacy modules are regular
C functions typically 2-3 times less efficient.
• The recent TI DMC updates are announced through controlSUITE since 2010.
• Legacy is motor control specific whereas controlSUITE is more comprehensive system covering almost
all C2000 based applications.
The DMC projects in the Legacy and ControlSUITE are given in the table below:
