읽어 볼 걸 찾아 보고 있는데

일단 클럭 도메인을 통해서 전원소비를 줄일수도 있는 듯?

Avalon Memory Manager와 nios 클럭 서로 다르게 줄 수 있다.

13. Power Optimization

 In this design, a Nios® II processor acts as the controller operating at 50 MHz. A DMA controller operating at 100 MHz manages the data path, and reads and writes data buffers that also operate at 100 MHz.
