VHDL code Question

if u just need a single tone, then u can store the values for the sine in a ROM and throw it out on each clock.

If u need different tones to be generated, then u have to implement a Phase Accumulator also.This concept u can get it easily if u go through any of "DDS" or "NCO" implementation. search in google for NCO or DDS.
