Flexible system integration to improve thermal properties

Abstract:

In an embodiment, an interposer includes multiple integrated circuits coupled thereto. The integrated circuits may include processors and non-processor functionality that may have previously been integrated with the processors on an SOC. By separating the functionality into multiple integrated circuits, the integrated circuits may be arranged on the interposer to spread out the potentially high power ICs and lower power ICs, interleaving them. In other embodiments, instances of the integrated circuits (e.g. processors) from different manufacturing process conditions may be selected to allow a mix of high performance, high power density integrated circuits and lower performance, low power density integrated circuits. In an embodiment, a phase change material may be in contact with the integrated circuits, providing a local reservoir to absorb heat. In an embodiment, a battery or display components may increase thermal mass and allow longer optimal performance state operation.
