Latch Module for Abnormal Information Output in Computer Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer systems lack a reliable mechanism to record operation status information during abnormal events, such as overheating, leading to difficulties in determining the cause of system failures since the microprocessor may not function in such scenarios.
Innovation Solution
An abnormal information output system comprising a latch module connected to sensors and hardware devices to capture operation status information during abnormal operations and a BIOS module to analyze and output this information once the system returns to normal, allowing for the determination of the cause of malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a microprocessor is used to record operation status information, then the system can monitor hardware status, but the microprocessor cannot record abnormal events when it fails
Solution Approach 1:
The patent introduces a latch module as an intermediary component between the microprocessor and the abnormal event recording function. The latch module independently captures and stores operation status information when abnormal events occur, serving as a mediator that ensures information is preserved even when the microprocessor fails. This resolves the contradiction by providing a backup recording mechanism that operates independently of the microprocessor's operational status.
Solution Approach 2:
The latch module is pre-configured to automatically capture and latch operation status information when abnormal events are detected, before the microprocessor may fail or lose recording capability. This preliminary action ensures that critical abnormal event information is preserved in the latch module, preventing information loss even if the microprocessor subsequently fails.
2Reliability
If a baseboard management controller (BMC) sub-system is used to record operation status information, then abnormal events can be reliably recorded, but the system cost increases
Solution Approach 1:
The patent extracts the abnormal event recording function from the complex BMC sub-system and implements it using a simple latch module. By taking out only the essential function of capturing and storing abnormal event information, the system achieves reliable recording without the need for a full BMC sub-system, thereby reducing device complexity and cost while maintaining the core capability of recording abnormal events.
Solution Approach 2:
The latch module serves as a simple, cost-effective component that performs the specific function of capturing abnormal event information. Rather than deploying an expensive and complex BMC sub-system, the patent uses a inexpensive latch module that can be easily integrated into the system, providing the necessary reliability at a lower cost and complexity level.
