Hi all,
what are the steps towards optimizing the G.726
speech codec C code on C64x processor.Is it necessary
to implement the functions
in hand coded assembly to achieve efficient MIPS.
Thanks and Regards,
Mayank Agarwal

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
- int instead of char, short if possible.
- used keyword restrict with pointers.
- 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
