US 2024/0176406 A1 · Preemptive Processor Power Supply Regulator Feedback Modulation to Mitigate Voltage Overshoot and Undershoot

Abstract

Compilers for some processor architectures, in particular, deterministic processors, can predict exact processor current demands for a time period as brief as a few nanoseconds. Information generated by such compilers of future excessive current demand is used by the embodiments disclosed herein for predictive mitigation of voltage overshoot and undershoot. This Abstract and the independent Claims are concise signifiers of embodiments of the claimed inventions. The Abstract does not limit the scope of the claimed inventions.

Claims4

Dependent claims

A more efficient/useful electronic structure for a tensor processor, comprising:

a compiler for generating information about power requirements during execution of an algorithm, and a specific timing of these power requirements, for the algorithm to be executed on a processor, the information generated before the execution of the algorithm and a power supply adapted to control voltage droops and overshoots in response to the information communicated from the compiler to the tensor processor and supplied to the tensor processor during the execution of the algorithm.

Dependencies are inferred from the claim text.
