FPGA Configuration and HPS Booting
The FPGA fabric and HPS in the SoC FPGA must be powered at the same time. You can reduce the clock frequencies or gate the clocks to reduce dynamic power.
Once powered, the FPGA fabric and HPS can be configured independently thus providing you with more design flexibility:
- You can boot the HPS independently. After the HPS is running, the HPS can fully or partially reconfigure the FPGA fabric at any time under software control. The HPS can also configure other FPGAs on the board through the FPGA configuration controller.
- Configure the FPGA fabric first, and then boot the HPS from memory accessible to the FPGA fabric.
