I want to know the optimization code for following c source code:
so here i should range from 0 to 15 but if i goes beyond 20 then it should remain as 15.
Here I have hint as to use bitwise operator to optimize like i=(p*q<<12)& 0x000F;
Also please anyone can tell me the ebooks or links or good book to start with the optimization of c source code.
I am the beginner in the C source code optimization and speech coders.
Please help me out to optimize the source c codes...
also different tricks to optimize the arithmetic operations any links please help...
