Patent Overview — US 8,898,494 B2

Title: Power budgeting between a processing core, a graphics core, and a bus on an integrated circuit when a limit is reached.

Patent number / application: US 8,898,494 B2, application US 13/398,641; published as US 2013/0159741 A1.

Inventors: Travis T. Schluessler and Russell J. Fenger. Original assignee: Intel Corp. A reassignment to Daedalus Prime LLC is listed on 2022-06-06.

Dates (from the supplied text): priority date 2011-12-15; filed 2012-02-16; published 2013-06-20; granted 2014-11-25; legal status Active, with adjusted expiration 2032-04-01. Google's status and priority entries are expressly described as assumptions, not legal conclusions.

Purpose (as stated in the excerpt): The disclosure "pertains to energy efficiency and energy conservation in integrated circuits, as well as code to execute thereon, and in particular but not exclusively, to balancing power and performance between processing elements and/or a communication bus." The background notes that a system on chip (SOC) with a host processor and graphics processor "usually implements power savings policies individually and separately," and that a package-wide power policy "often only contemplates assumed power requirements for each of the individual devices without balancing power and performance amongst asymmetric cores to achieve maximum overall performance."

Plain-language scope: Per the title and definitions, the patent addresses budgeting power across three on-chip consumers — a processing core, a graphics core, and a bus — when a power limit is reached. The excerpt lists figure topics only: logical representations of a system with a multi-processing element processor and integrated graphics processor (FIG. 1) and of computer system configurations (FIGs. 2–4), with FIG. 5 beginning an unspecified embodiment. Classifications include G06F1/3203, G06F1/3234, G06F1/3253 (power saving in bus), G06F1/329 (task scheduling), and G06F9/5094 (resource allocation considering power or heat).

What the excerpt does not establish: No claims, detailed description, or figure content are included, so the specific budgeting method, claim scope, and FIG. 5 subject matter are not shown. No prior art is identified here.
