SYSTEMS AND METHODS FOR INITIALIZING AND CALIBRATING ASYMMETRIC DIE-TO-DIE INTERFACES

原文（中文）

Systems and methods for initializing and calibrating asymmetric die-to-die (D2D) interfaces are described. As an example, during the calibration of a parameter, a calibration finite-state machine (CAL FSM) can perform certain measurements and adjustments. Once a stage of calibration is finished, the CAL FSM can communicate this information to a cluster FSM. The cluster FSM can then communicate to the node FSM the completion status. Once all the clusters have communicated to the node FSM that they have finished the current stage of calibration, the node FSM advances to the next stage of calibration and communicates to the pertinent cluster FSMs to advance, which in turn communicate to the CAL FSMs within the cluster to advance to the next stage of calibration. The clusters that are communicating in one direction are now able to receive the calibration stage information via other clusters that are communicating in the other direction.
