You can use a dual-ported RAM. One side of the RAM can appear as an Avalon-MM slave, and you can then read/write to the RAM. The other side of the interface can then be accessed by an FSM that reads data from RAM and sends it to your ADC. You can get 'fancy' by making this an Avalon-ST streaming source, and making your ADC an Avalon-ST sink, and then you can wire them altogether in SOPC Builder or Qsys.
