Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to timely detect and address bus anomalies, leading to computation errors and hangs that can go unnoticed, affecting the reliability of functional components in data processing systems.
Innovation Solution
A bus anomaly detection method and apparatus that activates a detection state upon an access request, performs anomaly detection on response signals, records anomalies, and blocks or releases interruption signals as necessary to prevent errors, ensuring correct task completion and system reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anomaly detection is performed on response signals, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by activating a detection state before processing access requests, where the detection apparatus pre-configures anomaly detection mechanisms. When an access request is received, the system enters a detection state that monitors response signals for anomalies before they can cause computation errors or hangs, thus improving reliability without requiring complex real-time analysis during normal operation.
Solution Approach 2:
The patent introduces an intermediary detection apparatus that sits between the access initiating apparatus and access receiving apparatus. This intermediary monitors response signals without interfering with normal bus operations, detecting anomalies such as computation errors or hangs. The detection apparatus acts as a mediator that improves system reliability while maintaining simple integration with existing bus architecture.
2Measurement precision
If interruption signals are blocked during detection, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The patent implements periodic action by temporarily blocking interruption signals only during the detection state when anomalies are being monitored. The blocking is not continuous but periodic - activated when detection is needed and released when detection is complete. This ensures precise anomaly detection during critical periods while maintaining normal task processing efficiency during non-detection periods.
Solution Approach 2:
The patent applies dynamics by making the interruption signal blocking state dynamic rather than static. The blocking mechanism is activated and deactivated based on the detection state, allowing the system to adapt between high-precision detection mode (with blocking) and normal operation mode (without blocking). This dynamic approach balances measurement precision and productivity based on real-time system needs.

AI summary
A bus anomaly detecting method, processing method, apparatus, system, device, and medium. The bus anomaly detecting method includes: at an interface for connecting a bus, activating a detection state in response to an access initiating apparatus sending an access request to an access receiving apparatus so as to, in the detection state, perform anomaly detection on response signal fed back by the access receiving apparatus for each access request, and block an interruption signal sent by the access initiating apparatus; in response to a response signal corresponding to an access request having an anomaly, terminating the detection state, recording bus anomaly information, and sending an interruption signal; and in a case where the response signal corresponding to each access request sent by the access initiating apparatus is received and has no anomaly, terminating the detection state to stop blocking the interruption signal sent by the access initiating apparatus.
