Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing systems face challenges in determining circuit power requirements due to variable processing iterations, leading to ambiguity and potential overcurrent conditions, often resulting in the use of more expensive power dissipation methods than necessary.
Innovation Solution
The implementation of a data processing system that includes a noise predictive calibration circuit, data detector circuits, and a power governing circuit, which modifies the operation of these components to prevent overcurrent conditions by disabling or reducing the update rate of slow-changing circuits such as adaptive calibration circuits when multiple detector and decoder circuits are operating simultaneously.

Engineering Contradiction Analysis
1Productivity
If multiple data detector circuits and decoder circuits are operated simultaneously to increase processing capability, then productivity is improved, but power consumption increases leading to overcurrent conditions
Solution Approach 1:
The patent implements dynamic control of calibration circuits by a power monitor and operation decimation controller. When overcurrent conditions are detected during simultaneous operation of multiple detector and decoder circuits, the system dynamically adjusts the operation of calibration circuits, transitioning them from continuous operation to periodic or disabled states, thereby reducing power consumption while maintaining productive circuit operation
Solution Approach 2:
The system changes operational parameters of calibration circuits based on power conditions. The power monitor detects overcurrent conditions and the operation decimation controller modifies calibration circuit operation parameters (such as update rates or enable/disable states) to reduce current consumption while allowing multiple detector and decoder circuits to operate simultaneously for maintained productivity
2Reliability
If adaptive calibration circuits operate continuously to maintain optimal performance, then reliability is improved, but power consumption increases causing overcurrent conditions
Solution Approach 1:
The patent implements periodic operation of calibration circuits instead of continuous operation. The power monitor and operation decimation controller cause calibration circuits to operate periodically at reduced update rates when overcurrent conditions are detected, maintaining sufficient reliability for circuit performance while significantly reducing power consumption to prevent overcurrent conditions
3Reliability
If expensive packaging with high power dissipation capacity is used to prevent overcurrent conditions, then reliability is improved, but device cost increases
Solution Approach 1:
The patent implements a self-service power management system where the power monitor continuously monitors power consumption and the operation decimation controller automatically adjusts calibration circuit operation to prevent overcurrent conditions. This self-regulating system eliminates the need for expensive high-power dissipation packaging by dynamically adapting circuit operation to actual power requirements, thereby reducing device cost while maintaining reliability
