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.


Fine, but first find a microcontroller with such a fast (minimum 60MHz)
DAC. Even if you do you'll spend many times the cost of a simple
microcontroller plus DDS chip system - and you won't rival the cheaper
system's performance until your DAC can work at several times 60MHz.
