Peak power management of dice in a power network

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

• receive, from each of a plurality of dice in a power network, a first activity state value indicating that the respective die is in a high current state, a second activity state value indicating that the respective die is a moderate current state, or a third activity state value indicating that the respective die is a low current state, wherein the received activity state values include at least one of the second or the third activity state value;
• determine a sum of the activity state values;
• determine a remaining budget by subtracting the sum from a maximum value;
• select an activity state with an activity state value that is within the remaining budget based upon the sum;
• and
• send, to the plurality of dice, an activity state value corresponding to the selected activity state.

A system comprising:

• a first die in a power network;
• and
• a plurality of second dice in the power network coupled to the first die via a bus, wherein the first die includes a power manager to:
• receive, from each of a plurality of second dice, a first activity state value indicating that the respective die is in a high current state, a second activity state value indicating that the respective die is a moderate current state, or a third activity state value indicating that the respective die is a low current state, wherein the received activity state values include at least one of the second or the third activity state value;
• determine a sum of the activity state values;
• determine a remaining budget by subtracting the sum from a maximum value;
• select an activity state with an activity state value that is within the remaining budget based upon the sum;
• and
• send, to the plurality of second dice, an activity state value corresponding to the selected activity state.
