Hi Mayank,
 
Maximum out of the optimization on C64x with C code only comes from variable declarations, simple intrisincs usage,usage of proper pragmas and restructuring the computational loops.
Like try to use
  1. int instead of char, short if possible.
  2. used keyword restrict with pointers.
  3. pragmas like MUST_ITERATE(10,40,4)
Much more techniques have been throughly presented int he following two documents: spru425a, spru198g.
Hope you find the above techniques and the material usefull.
 
Thanks & regards,
Venugopala Krishna
