Abstract
Techniques described herein generally include methods and systems related to the use of processors that include graphene-containing computing elements while minimizing or otherwise reducing the effects of high leakage energy associated with graphene computing elements. Furthermore, embodiments of the present disclosure provide systems and methods for scheduling instructions for processing by a chip multiprocessor that includes graphene-containing computing elements arranged in multiple processor groups.
Claims13
A chip multiprocessor, comprising;
- a first group of processor cores disposed on a die, wherein the first group of processor cores includes graphene-containing computation elements;
- a second group of processor cores disposed on the die, wherein the second group of processor cores includes a lower percentage of the graphene-containing computation elements than the first group of processor cores;
- and
- a third group of processor cores disposed on the die, wherein the third group of processor cores includes a lower percentage of the graphene-containing computation elements than the second group of processor cores, and wherein,
- the first group of processor cores are high-speed processor cores relative to the second group of processor cores and the third group of processor cores,
- the first group of processor cores are configured to operate when at least some processor cores of the second group of processor cores and the third group of processor cores are configured to be gated,
- each processor core of the third group of processor cores is arranged to facilitate thermal isolation of each processor core of the first group of processor cores such that at least one processor core of the third group of processor cores is disposed in between every two adjacent cores of the first group of processor cores, and to facilitate thermal isolation of each processor core of the second group of processor cores such that at least another processor core of the third group of processor cores is disposed in between every two adjacent cores of the second group of processor cores,
- the facilitation of the thermal isolation of each processor core of the first group of processor cores and each processor core of the second group of processor cores reduces an effect of leakage energy that is associated with the graphene-containing computation elements, and
- at least one processor core of the second group of processor cores and the at least one processor core of the third group of processor cores are disposed between every two adjacent cores of the first group of processor cores.
