Abstract
A heterogeneous three-dimensional (3-D) stacked apparatus is provided that includes multiple layers arranged in a stacked configuration with a lower layer configured to receive a board-level voltage and one or more upper layers stacked above the lower layer. The heterogeneous 3-D stacked apparatus also includes multiple tiles per layer, where each tile is designed to receive a separately regulated voltage. The heterogeneous 3-D stacked apparatus additionally includes at least one layer in the one or more upper layers with voltage converters providing the separately regulated voltage converted from the board-level voltage.

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.
A method of controlling power delivery in a heterogeneous three-dimensional stacked apparatus, comprising:
- reading a voltage control table defining voltage requirements 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;
- scanning, with control logic disposed at one or more layers of the heterogeneous three-dimensional stacked apparatus, the voltage control table for changes;
- in response to locating changes in the voltage control table, calculating voltage regulation commands for voltage converters in the heterogeneous three-dimensional stacked apparatus;
- and
- distributing the calculated voltage regulation commands to the voltage converters to control voltage on a tile basis and establish interconnectivity among the voltage converters by connecting active voltage converters and bypassing inactive voltage converters.
