3.2. Arria® 10 EMIF Sequencer

The EMIF sequencer for Arria® 10 devices is fully hardened in silicon, with executable code to handle protocols and topologies. Hardened RAM contains the calibration algorithm.

The sequencer is responsible for the following operations:

  • Initializes memory devices.
  • Calibrates the external memory interface.
  • Governs the hand-off of control to the memory controller.
  • Handles recalibration requests and debug requests.
  • Handles all supported protocols and configurations.
