1. A three-dimensional power delivery controller for power delivery management in a heterogeneous three-dimensional stacked apparatus, comprising:

  • a voltage control table defining voltage requirements, power and temperature ranges collected at run time, threshold values and conversion efficiencies for separate tiles of a heterogeneous three-dimensional stacked apparatus, the heterogeneous three-dimensional stacked apparatus comprising multiple layers arranged in a stacked configuration with multiple tiles per layer; and

    control logic, disposed at one or more layers of the heterogeneous three-dimensional stacked apparatus, the control logic configured to scan the voltage control table for changes, calculate voltage regulation commands for voltage converters in the heterogeneous three-dimensional stacked apparatus, and distribute the calculated voltage regulation commands to the voltage converters to control voltage on a tile basis.
