Designing a DDS and Phase Calculator Using CORDIC in Verilog
Direct Digital Synthesizer (DDS)
A DDS generates programmable complex tones. The output frequency (f_{out}) is a functon of the system clock (f_{clk}), accumulator width (N), and frequency control word (K):
[f_{out} = \frac{f_{clk}}{2^N} \times K]
The phase accumulator computes (\theta(n) = (K \times n) \bmod 2^N). The complex output is:
[y(n) ...
