IC Security Control Architecture for High-Volume Error Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing architectures for integrated circuits are unable to efficiently collect and process a large volume of error data due to limited space for wiring, leading to inefficiencies in error management.
Innovation Solution
A security control apparatus and method that groups multiple target control modules into a single data collection module, allowing error data and check codes to be processed through a centralized security control module, reducing the need for direct connections between the control module and each individual target module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security control module is directly connected to each target control module individually, then error data collection is straightforward, but the quantity of wires increases excessively
Solution Approach 1:
The patent merges multiple target control modules into groups, where each group is connected to a single collection module. This consolidation reduces the number of direct connections required to the security control module, thereby decreasing wire quantity while maintaining error data collection capability across all modules.
Solution Approach 2:
The collection module serves as an intermediary between the grouped target control modules and the security control module. It collects error data from multiple source modules and forwards consolidated data to the security control module, eliminating the need for direct connections from each source module to the security control module.
2Device complexity
If multiple error data sources are collected through a centralized architecture, then wire quantity is reduced, but the architecture cannot support huge numbers of error data
Solution Approach 1:
The system segments the collection function by introducing intermediate collection modules that handle data from specific groups of target control modules. This segmentation allows the security control module to receive processed data from multiple collection modules simultaneously, scaling the system's error data processing capacity while maintaining a manageable wiring structure.
Solution Approach 2:
The patent introduces a hierarchical dimension to the data collection architecture, organizing modules into multiple levels: target control modules at the bottom level, collection modules in the middle level, and the security control module at the top level. This multi-level structure enables the system to handle huge numbers of error data sources without requiring excessive direct connections to the top-level security control module.
