Power and Clock Control Module Standby Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power management techniques in electronic devices are difficult to design and verify, leading to unpredictable and unstable operation, and do not effectively reduce power consumption in a simple and reliable manner.
Innovation Solution
A power and clock control module (PCCM) is introduced to manage the initiation of a standby mode in electronic devices by coupling with an initiator module, using standby and wait signals to limit or remove power and clock signals, allowing for reduced power consumption while preventing edge condition errors through controlled signal activation and deactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If current power management techniques are used to reduce power consumption, then power consumption decreases, but the system becomes difficult to design and verify, leading to unpredictable and unstable operation
Solution Approach 1:
A dedicated power management module is introduced as an intermediary component that sits between the processor and power sources. This module independently manages power distribution to various components, simplifying the overall system design while ensuring stable and predictable power control, thereby resolving the contradiction between power reduction and operational reliability
2Loss of energy
If power management techniques are implemented to reduce power consumption, then energy efficiency improves, but the design and verification complexity increases
Solution Approach 1:
The power management functionality is segmented into a dedicated standalone module rather than being distributed throughout the system. This segmentation consolidates the complexity into a single verifiable unit, making the overall system easier to design and verify while maintaining effective power consumption reduction capabilities
3Use of energy by moving object
If clock signals are stopped to reduce power consumption, then power usage decreases, but the system may experience unpredictable operation
Solution Approach 1:
The power management module implements feedback mechanisms that continuously monitor system state and component activity levels. Based on this feedback, the module intelligently controls clock signal distribution, stopping clocks to inactive components to reduce power while maintaining predictable and stable operation through coordinated control

AI summary
An apparatus and method for controlling standby mode in an electronic device. In standby mode, power and clock signals are reduced or stopped to conserve power. The apparatus includes an initiator module coupled to a power and clock control module (PCCM). When the initiator module meets conditions for standby mode, the initiator module sends a standby signal to the PCCM and does not interact with other initiator, target, or interconnect modules. When the PCCM communicates a wait signal, the initiator module enters standby mode. When the initiator module detects a wakeup event, the standby signal is deactivated. In this state, the initiator module may process information but may not interact with other modules. When the PCCM deactivates the wait signal and returns power and clock signal to steady state levels, initiator module may resume normal operation.
