Engineering Contradiction Analysis
1Stability of the object's composition
If the decoder works at a long-term stable working point, then the decoding stability is improved, but when optical channel status fluctuates, the working point fluctuates between stable and extreme points causing large power consumption fluctuation
Solution Approach 1:
The patent applies dynamics by making the turn-off probability adjustable rather than fixed. The decoding controller dynamically adjusts the turn-off probability based on optical channel status, transitioning between stable working point and extreme working point smoothly. This dynamic adjustment prevents abrupt working point fluctuations that cause large power consumption variations, while maintaining decoding stability through controlled probability modulation.
Solution Approach 2:
The patent changes the parameter of turn-off probability from a fixed value to a dynamically adjustable parameter. By modifying the turn-off probability parameter in response to optical channel status changes, the system prevents abrupt transitions between working points, thereby reducing power consumption fluctuation while maintaining decoding stability.
2Productivity
If the turn-off indication from previous-stage decoder is immediately effective on next-stage decoder, then the decoding efficiency is improved, but rapid fluctuation in power consumption occurs
Solution Approach 1:
The patent introduces an intermediary mechanism - the decoding controller with probabilistic processing - between the previous-stage decoder and next-stage decoder. Instead of immediately transmitting turn-off indications, the controller applies probabilistic judgment based on optical channel status. This intermediary layer smooths out abrupt transitions, preventing rapid power consumption fluctuations while maintaining overall decoding efficiency through intelligent probability-based control.
Solution Approach 2:
The patent applies preliminary action by having the decoding controller pre-process turn-off indications before they reach the next-stage decoder. The controller performs probabilistic evaluation in advance based on optical channel status, determining whether to transmit the turn-off indication. This preliminary probabilistic filtering prevents abrupt and potentially harmful immediate transmissions, smoothing power consumption variations while preserving decoding efficiency.
3Reliability
If multiple decoders are used in sequence, then the decoding reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the functions of multiple decoders with a centralized decoding controller that manages turn-off probability for all stages. Instead of independent complex decoder systems, the controller coordinates turn-off decisions across multiple decoder stages using unified probabilistic control based on optical channel status. This merging approach maintains high decoding reliability through multi-stage processing while reducing overall system complexity through centralized intelligent control.

AI summary
A decoding system, a decoding controller, and a decoding control method are provided. In the decoding system, a decoding controller (20) is disposed between two adjacent decoders (10, 30). The decoding controller (20) determines whether to perform turn-off based on a non-turn-off indication received by a previous-stage decoder, a turn-off indication output by the previous-stage decoder, and historical turn-off probability statistics. This is equivalent to adding a buffer zone between the two adjacent decoders (10, 30). Therefore, the turn-off indication output by the previous-stage decoder is prevented from being immediately effective on a next-stage decoder, and rapid fluctuation in power consumption of the decoder is mitigated.
