Fast Sin/Cos using a pre computed translation array

Question

I have the following code doing Sin/Cos function using a pre-calculated memory table. in the following example the table has 1024*128 items covering all the Sin/Cos values f

Answer 1

If you have to compute it so many times,

1. Use a processor-specific math library like the IKML or ACML and
   1. Compute the values in groups (vectors).
   2. When you need both, always compute the sin and cos of a value at the same time.
2. Check your algorithm complexity and implementation design.
3. Make sure you're using all the processor has to offer - x64 architecture, plus any vector instructions that would help.
