Problems solved by technology

[0005] Since each processing element independently allocates and accesses shared resources, this approach becomes increasingly cumbersome for scenarios with multiple processing elements, making power management effectively a game-theoretic problem

Embodiment Construction

[0020] refer to figure 1 , shows a conventional system-on-chip 10 comprising conventional functional resources / storage resources 12 , such as memory banks, with a low power consumption controller 14 . Central manager / low power controller 16 of system on chip 10 is configured to manage low power consumption of all processing elements 18 and resources 12 on SoC 10 . According to different system requirements and loads, the controller 16 selectively puts the processing element 18 and the resource 12 into a predefined low power consumption mode through a handshake between the low power controller 16 , the resource 12 and the processing element 18 . The low power controller 14 for the resource 12 handles the low power handshake with the controller 16 to receive the appropriate low power control command and to act accordingly so that the resource 12 is in the state indicated by the low power control command corresponding status. A resource 12 behaves like a virtual slave and does ...

Abstract

Function resources / memory resources and an associated resource controller configured to assign a first portion of the function resources / memory resources to at least one processing element in response to an access request from the processing element. The resource controller changes a power mode of the first portion of the function resources / memory resources as a function of the first portion assignment, and leaves an unassigned portion of the function resources / memory resources in a power down mode in a self-governing nature. The resource controller enables the processing element to access the first portion of the function resources / memory resources in response to the access request received from the processing element. The function resources / memory resources, resource controllers and one or more processing elements may comprise a system on a chip (SoC).

Description

[0001] This application claims priority to U.S. Nonprovisional Patent Application No. 14 / 601981, entitled "Low Power Control and Management of Driver Access-Based Resources for Multi-Core Systems on a Chip," filed January 21, 2015 , and this U.S. nonprovisional patent application claims U.S. Provisional The priority of the application, the entire content of which is incorporated in this application by reference. technical field [0002] The present disclosure relates generally to power consumption management, and more particularly to power consumption management in a system-on-chip (SOC) such as a functional resource / memory resource controller / scheduler or the like. Background technique [0003] Advocate Green is a worldwide initiative to make the world a better place to work and live. Information, communication and telecommunications are essential and ubiquitous for everyone's daily life. [0004] Compared with the traditional architecture in which a single DSP / CPU proces...
