What about the Cyclone III EP3C25 Starter Board Test Design? can I implement a DUC and DDC (NCO,Filters,Mixer) and interconect it to an HSMC board?

This kit:
http://www.altera.com/products/devkits/altera/kit-cyc3-starter.html Any FPGA can be used to implement an NCO, DUC or DDC. Ultimately you are only limited by the resources your DSP logic requires, and whether you want to access external signals. DSP logic can easily be tested using RAM for a DSP input data source, and for DSP output data sink.
