IEEE 1924.1-2022

This recommended practice specifies a set of guidelines for the development of power-proportional digital architectures so that energy is only consumed when computations are underway. Digital architectures could encompass individual devices such as CPUs and systems on chip (SoCs), or specialized computing platforms such as smartphones, smartwatches, and individual servers, or larger systems and networks of distributed compute and data servers. These architectures could consist of components such as processors, specialized accelerators, memory, interconnects, storage, networks, and power supplies. In power-proportional power supplies, various techniques can be used to conserve and store energy when computation is halted, keeping it available for immediate use upon restart. The objective of such power supplies is to respond to nanosecond variations in the computing load in the presence of complementary metal-oxide semiconductor (CMOS) static power dissipation.
