Thank you for your suggestion.
Assuming that DDS is Direct Digital Synthesis, I'm not sure anything needs to
be lashed to anything.

Just use a phase accumulator in a single DWORD or
whatever native data size gives adequate resolution. Then just feed a DAC,
assuming the processor has one. I think very many of them do.
