3.4.2. Intel® Agilex™ Hard Memory Controller Rate Conversion Feature
To improve efficiency and help reduce overall latency, the hard memory controller and PHY run at half rate when the rate conversion feature is enabled. User logic runs at quarter-rate.
The rate conversion feature is enabled automatically during IP generation whenever all of the following conditions are met:
- The hard memory controller is in use.
- User logic runs at quarter-rate.
- Running the hard memory controller at half-rate does not exceed the fMax specification of the hard memory controller and hard PHY.
When the rate conversion feature is enabled, you should see the following info message displayed in the IP generation GUI:PHY and controller running at 2x the frequency of user logic for improved efficiency.
