duplicated question:
 
sdm: small memory
ldm: large memory
 
For DSP there are 2 memories: DATA and CODE
DATA  is defined by x
CODE is defined by p
For each memory there are:
 External, flash, ram and for DATA IO.
So by this way xRAM is the RAM from DATA and pRAM is the RAM from CODE
 
for details I recommend you to create a project with Processor Expert.
Under Processor Expert menu you can open the Memory Map.
Some information is given in the cmd file too.
 
Hope this will help you.
